Battery life is superb but I don’t get all WhatsApp photos/image, calendar or todos from IOS. I have a tactix 7 pro and maybe I will change to Apple Watch Ultra 3
Battery life only I am not the target user, I don’t do sport ; and have a iPhone

I prefer the old software opposed to the new one which is trying to compete with Apple Watch Ultra by adding unnecessary features. I prefer the MIP display cause you’ll find more watch faces that will look and work better with the MIP display while the AMOLED limits you. Overall I have the Tactix 8 Amoled which I’m trying to get rid of and I’m very happy to be back with my Tactix 7 pro.
The Fenix 8 satellite edition does have better hardware. However is it worth the additional $500-$600 for satellite and being dive rated that’s up to you. For me it would be better to spend extra since I’m a scuba diver and the satellite connectivity is a nice peace of mind feature if you go out for hikes in the wilderness. I’m just holding off for a satellite enabled Tactix 8 but my Tactix 7 Pro Solar is one of if not my favorite piece of tech I own and works pretty well with the occasional hickup but mostly rock solid and I do like the feel of having actual buttons as opposed to the digital buttons on the newer models.
Ima be honest with you… don’t for a second believe the Garmins are super durable. It’s half garbage promotion portraying their build quality like it’s supposed to be all that but it’s like any other brand. Buttons stop working and hang up, I’ve had 3 watches exchanged through warranty due to that, a Fenix 6, and two Tactix 7 pro. Their DLC coating is hot garbage, the Tactix which was supposed to be their military applicable watch is made with such a light coat that edges just by touching them shine through of metallic silver within weeks. Any minor hit, grain or ding is an instant scratch that won’t go away on the DLC coating. Regular titanium is vastly better. Software is hit and miss, it’s the same hardware since 2001, maps and other things might bugg out due to not having enough processing power to handle all things at once even on their top of the line watches. Updates are regular but comes with buggs and massive battery drains at times. My tactix never recovered to last 28 days as it should after their updates. Certain 3rd party watchfaces drain battery even more so it just doubles down completely. And don’t let me start with their wrist bands and quality, 4 Tactix bands gone to shit, they start yo peal from the edges, Velcro just gives in after a few months… After 6 years and seeing them just adding premium on top of premium with all the issues they have is as of now a true banana fest. HQ has no idea wtf they are doing and what the audience wants.
6 years of garmin - Now switched to AWU3 for the last two months. Now as people mentioned, the extra insights and easy to go features of the Garmin are nice. You get your body battery, stress levels, heartrate every second recorded and so on is a big plus for a lot of athletes. Running features are also more developed with pacepro and so on, adding a HR strap enhances that even further. And don’t get me started in the flash light, best feature ever. Then again, I realized with the AWU3 that I less focus on metrics which in the end is just a algorithm made by the company to measure how you feel. It’s not always accurate and many people have said it plenty of times that things like body battery isn’t even close to being on target. At times it is, sometimes far off, same thing goes with sleep metrics. I run a little, 2-3 times a week then I do other activities and I hit the gym regularly. Bevel and Athlytic is enough for now, and I’d assume a running app will do things even better. Sleep metrics are far better on my AW3 then my old Fenix 6 or Tactix 7 pro. Seamless connectivity is by far the best feature with Apple, it just syncs automatically on the fly with health, your phone and other devices. Health is also better then expected, you can pull out plenty of metrics by diving in, trends and so on. The community is currently waiting for a major update to health, Apple has been teasing us so that could be a good step towards being a better tracker then it is. No HR strap needed, AirPods Pro 3 measure HR. Same goes with their Beats by Dre 2 earbuds, testing shows very good accuracy. In with the buds and start activity, it’s all working in the background seaminglessly. Lastly charging, I was an big advocate for Garmin due to their battery life. Switching to AWU3 is different, two days with daily exercise is what I can expect battery wise. Though what no one seems to mention is that the watch charges fast, 30 min before sleep or during showering will top up the watch easily. My Garmin charged for two hours, and the updates made the watch in the end to drain battery more and more. Quality wise both are fairly equal, but I do think apples AWU3 is a step up. Avoid black DLC coatings, it’s just as shit on both. My tactix lost its carbon black DLC on the edges with first 3-4 weeks, pissed me off. If you are only doing marathons, pacepro running, ultras.. I guess you should stick with a Garmin. Plenty of people still do marathons with their ultras, but then you need to charge more often. Your choice, whatever you pick enjoy it!
Yeah next step I to move away from garmin after 6-7 years. Every update eats battery, more issues added less fixed. My tactix 7 can’t even run any other IQ store watchface due to having massive battery drain. Despite full watch reset, reboots and so on it’s not last the 28 day as advertised.
Two differetns worlds. Very hard to compare. I have AWU and Tactix 7 pro. Usually switch them by which is more peak about the situation. Onestly i will not give up neither
Enduro 3 ~40 days (although lately my battery has been draining about 5-10% daily or at least it seems that way despite having not worn it in a while) Instinct 3 Tactical Solar ~40 days Tactix 7 Pro ~25 days
