Suunto Race S review, and why I am forced back to Garmin

I have had my Suunto Race S for a couple of weeks, and sadly am going back to Garmin:

THE GOOD

• The Race S looks GREAT. The size is perfect on my smaller 160mm wrists, and the styling is excellent. I'd go as far as saying it's the best looking sports watch. It's rugged, clean, the straps are amazing (and I love that they have some suitably sporty designs). It looks so good and the competition looks so bad that I was desperate to find some reasons to stay.
• The features are excellent for the money. Maps especially.
• Heart rate and GPS tracked fine for me. I don't use heart rate straps or anything like that, so I can't really be sure, but certainly everything looked reasonable on Strava etc.
• The app feels a bit simplistic but is presented well, vs Garmin's cryptic data nightmare.

THE BAD

• It's simply unusable for me as a running watch. I use Runna to build a training plan, and as soon as I've got some kind of structured workout it shits the bed. On the guide screen you can only see your current pace vs the target in the 'intensity zones' widget around the watch perimeter. You can't see your average pace for the interval, or interval number, or next interval details. You can customize a separate screen to show you the interval avg pace and interval number, but you can't add the interval target pace widget, so you wouldn't want to be in that screen anyway. What's more, the watch will not alert you if you're ahead/behind the target, you just have to keep looking at your watch, which is NUTS. It also doesn't count down toward interval start/end. I can only assume that no-one developing this watch has ever done a targeted interval workout, or at least never seen how the competition do it.
• Can't pause activity during the maps screen. Apparently you used to be able to, but they removed it inexplicably. The button doesn't do anything now!
• The turn-by-turn alerts are unusable. They consume the entire screen and overlap each other to the point where there's no choice but to not use them.
• It does not allow you to use a combo of miles for distance and metric (centigrade) for temp. The entire of the UK will want that.
• Absent product team. Firmware updates do come but people have been moaning on the forums about TBT, intervals, metric/imperial etc for years, with seemingly no progress.

I can't stress enough how much I wanted to stick with Suunto, as Garmin watches are ugly and chunky, but the intervals thing really is a killer. Even my Garmin FR45 does all this basic stuff, but I really don't want to spend more on another plastic toy Forerunner.
