Same. Both have plenty of scratches here.

I also don't see why an Apple Watch wouldn't survive all those mentioned things. Pretty sure I did all those things with an Apple Watch on, except for the specific 108 mile gravel race. But I don't see why it would fail that.

And both might absolutely scratch while climbing, and if you're unlucky and hit it in the wrong spot, also crack.

That said, if I were an athlete in any of those categories and did it all the time, I'd still absolutely choose a Garmin.
