Long battery; but wrist HR tracking is inconsistent.

I went from Pixel Watch 2 to Apex 2 Pr. You give up assistant is the big thing but get battery life in return which is way better because I only have to charge one or twice a month vs every day so I was rarely tracking my sleep because I had to charge every night.
I feel like Coros is almost there. Flashlight for sure is coming in a future watch (probably Vertix 4, then will trickle down to at least Apex 5). Design is obviously highly subjective, but I agree that Suunto has a cool design. However, I‘m digging the design of the Nomad and also the clean look of the Pace 4. Regarding more data in the web plattform or app. I‘m also very confident that they will add more stuff over time. Overall, going with Coros seems to be the best choice and it will only get better.
It's fantastic, using it regularly for mountain biking, hiking, climbing. Kinda like the styling and doesn't shout "coros" on the dial like the apex series. It's very light.
This is not the point. It was mentioned here that coros does "no Feature lock" if the hardware can support the feature. And this is not true. Touring mode is another example. Bouldering as well. And yes some people want to do touring or bouldering with a pace, why not!? But again the point is that Coros is doing feature lock. Personally I do not miss the fishing mode on my Apex.
How much battery life are we talking? I have an OG Apex and it easily gets me through a 100 for half the price of a Vertix. Guess it just depends on what features you're looking for; I want the bare minimum and Apex is great for me.
It's a great watch and will likely do everything you need it to do. I'm a runner and am contemplating an upgrade from my Pace 3 to the Apex, mainly for the longer battery life and topo maps (I'm doing some very long trail races). What sort of runs are you going to use it for? If budget is a consideration then the Pace 4 is an excellent choice, with almost identical features except battery life and mapping. Edit: The Pace Pro is also worth looking at - it feels more premium than the Pace 4 and is slightly cheaper than the Apex. My main reason for considering the Apex instead is that I have tiny wrists and the Pace Pro is pretty big.
