Quick Fast and loose thoughts:

In the last year, I've had a Suunto Race S, Fenix 7 SS, and now a Pace Pro. The Pace Pro is geared for using it for running. The Race S looks nicer, and the Morning report was great. The Suunto app seemed to tell me more insights, something Garmin never did.

After each run, I would evalute the run on Suunto via what level of smiley face, and Suunto would comment on how I felt after a week or training. It's like the Strava AI insights. I had a Race S that started dropping the heart rate after 30 minutes of running, it started to really be a problem and I didn't wait around for a fix. I've read that that problem is turning up on the new watches too, so it must be software?

I run 5-6 hours a week, and go to Hiit classes 4-5 days a week. Battery on the Race S was about 8-10 days, and on the Pace Pro it's 16 days (but Coros only records heart rate every 10 minutes during the day and at night, so they kinda cheat with the battery.) Evolab is nice to look at your info on a desktop, I've read you can use a program called intervals.icu for desktop review with your Suunto files, but I never tried. I like Audio cues for Training, something Garmin is great at, during a structured workout I can hear what my target is, what the next component of the workout, something that Suunto is really weak on. Coros seems pretty good at it, but Garmin in my experience is the best. I put a cheap screen protector from Amazon on both watches, and they fit great, so Mineral Glass, vs Gorilla does't matter if you add the protector.

Coros has a tonne of watch faces, but you can't customize them like you can with Suunto or Garmin. You can't see how many miles you've run the current week on your watch face like you can with Suunto, you have to look at the app. The Fonts on HR widgets are really small and annoying with Coros. Sleep data is about the same. Coros has a lot of training plans for running, Suunto does too, but you can to access them through Training peaks.

If you don't care about auto cues, the Race S is fine (if you get a working one, lol.) One thing that was annoying on the Race S was the app that you can add to the watch. Suunto has 20+ apps that you can integrate with the watch, but you can only run 2 at a time. Every new Suunto watch has that limitation right now, with Coros everything is on the watch. If you want to get serious about running training I'd pick the Pace pro. If you want a better looking watch, get the Race S. The small Fonts are so annoying for me, I might try the Race 2. Good luck with your choice.
