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.

the sapphire screens are incredibly resilient. mine looks brand new and is several years old. tested against plenty of bouldering

They are, they still scratch though (just google e.g. Fenix 7 Sapphire scratches). It's also not on all models. I guess part of it is also just layers on top of it scratching and not the sapphire itself.

But, Apple Watch Ultras and also Titanium models since Series 6? ship with Sapphire crystal too.
