Not only 1 right answer. Coros, suunto, polar are all great watches and honestly it comes down to user. I have suunto vertical which have medicore WHR, their 2nd version of vertical 2 and race 2 improved that. But coros vertix, apex 4 or pacer pro are also great options. Consider some models from polar aswel, like grit x2 pro, vantage v3, etc. Garmin have lots of options aswel with their forerunner and fenix and enduro series. My suggestion would be to check out dcrainmaker reviews and some yt reviews to see what watch can offer you. Then download their software and play on your phone to see how good/bad software fells for you. I am unaware what ios integration will be since i am an android user soo yea. And yea at the end its realy user based as long as you go with watch with dual band gps systemy onboard maps, and other stuff. Garmin is leading in maps since only on their watches you can reroute your route on watch itself, other brands requirw phone to do that + garmin have the most smarr functions. Soo yea also i am suunto user soo i would say suunto but some1 else might dislike suunto soo again not only 1 answer but many options. Garmin is the best but some dislike their app which is harder to use than some others plus price. Suunto is behind in smart functions + can be buggy (mine is flawless but many have problems with newer watches), coros i ve heard lots of complains witz their sensors for alltitude and gps but that might be just users who dont know how to use watch properly, etc. Soo yea read some reviews 1st.

Eh, tech is becoming more modern. Most company’s have software put in place to avoid pixel burn or by the time it happens you get a new device anyways.. Let’s be honest, you are going to need the same watch face for 5+ years of AOD to maybe have an issues.. they have pixel shifting and when I take my Coros pace pro off at night or to charge it shuts the screen off.. I think this is just another thing die hard MIP folks use as a reason to keep using an outdated tech. Suunto vertical 2 with a large amoled display is literally getting the same battery life as an equal size MIP. Also, I think for what it’s worth the Amoled display looks higher quality and provides a better experience.. that MIP is shit in the dark without raise to wake. Meanwhile my AOD I can glance down without raising arm in that gesture all MIP fans complain about, I can see what time it is.. It’s all disposable tech that’s built well enough to life it’s life span of usefulness. If it lasts 5 years before shitting the bed it’s doing pretty good and honestly most modern watches will probably last thing long and still function fine..
They are all three good watches (with their own fan base) I had the Apple Watch Ultra, variaous garmins and Suunto and now using the Suunto Vertical 2. Just get the one you like the most. Can’t go wrong. Watch some YouTube reviews- find out the good and less good things. They all do what they have to do.
I'd recommend a Suunto for the long-term investment in a platform and training system. Suunto, having been acquired by a Chinese company, has been infused with cash and this has played out in their app development as well as the watches they've been releasing. The Vertical 2 (AMOLED) virtually matches the first gen. Vertical hour to hour in battery life. Not to mention the Run which is the best value fitness watch on the market at this time. Suunto Coach is a good way to structure your training and the Suunto Plus store offers a ton of utility to Suunto watches (sans Run). On the flip side, Polar has floundered in recent years, lacking innovation and repackaging features into new hardware. The new M3 is a nice looking watch and is the best value of their newest releases, but they are so far behind in the digital realm, it's honestly depressing. Sure, they are updating Flow, but it feels too little too late. They have some training guidance, but unless FitSpark has had a MASSIVE update I've missed, it recommends really simple workouts that lack adaptation to current training which something like Gemini or ChatGPT could outclass given the right prompts.
So are Suunto's Vertical 2 or Race 2. With the latest update they gained automatic transition for triathlon. I think the app is even better comparing your activites over time. Garmin on the other hand does a lot of automatic detecting things and bombarding you with metrics that might be relevant and accurate or not. It's just your own preference... 
>How is the overall integration between the Vertical 2, and an iPhone? suunto does not respect focus modes. eg, if you have DND on your iphone when you sleep, or a focus mode whilst at work, or whatever - suunto doesn't care and will send you all notifications. you can either turn notifications on or off, unlike garmin/aw. also, reading a notification on your watch does not clear it on your iphone, unlike garmin/aw. so you'll see the same notifications twice. >How is the app? How simple is it to finish an activity and upload it to Strava or Trainingpeaks? all automatic but be aware that there's a longstanding bug with suunto workout uploads: [https://forum.suunto.com/topic/12624/laps-are-not-exported-from-app-to-strava-and-fit-file-correctly-breaks-runna](https://forum.suunto.com/topic/12624/laps-are-not-exported-from-app-to-strava-and-fit-file-correctly-breaks-runna) >How easy is it to use the app to plot a route while in a new city, or a trail run, send that route to the watch, and then follow directions on the watch while running or cycling? personally i hate the route planner on the app, but there is a beta online thing: [https://routeplanner.suunto.com/](https://routeplanner.suunto.com/) turn-by-turn directions on the watch are ass IMO. i turned them off. the mapping is good, other than that, although there is a zoom/trails bug that may or may not be a concern: [https://forum.suunto.com/topic/13311/map-rendering-and-trail-visibility-after-software-update-2.43.8-.12](https://forum.suunto.com/topic/13311/map-rendering-and-trail-visibility-after-software-update-2.43.8-.12) >Finally, does Suunto offer any type of 'try it for 100 days' thing where I could order a Vertical 2 and see how I like the watch and the ecosystem without being stuck with a $1000 watch in the event I want to stick with Apple? i would confirm with your local cs agent but at least for the UK i was able to return a used watch within the 30 day returns window.
