[OnePlus 8T Accessories] rcummings100:
I have both. I'm kind of a case hoarder, trying to find the perfect case. I drop my phone often because my hands randomly spasm.

Which case is better comes down to 1 question: will you be using anything other than your phone in the case?

The OtterBox + glass screen protector did well. The UAG + screen protector didn't do nearly as well. It broke more often, faster.

If you're sticking anything additional in, like a thin metal plate for sticking to magnetic holders like you put in your car, it will be too thick for either case. I rather like using a lanyard and found this thin pad that sits behind a phone and had a strap coming out the charging hole of your case with a small keychain loop....even that's too thick. The metal sheet or my thin pad causes the screen protector to protrude too far out from the case. 1 drop and they'll break.

Bare phone, either will work very well.

If I had to pick between them protection wise, the OtterBox probably has it.

If you have your heart set on the UAG, I have a better suggestion: get the Poetic Affinity case. It's less than half the price and better IMO than the UAG.

A case very similar to the OtterBox but maybe with BETTER protection is the Spigen Tough Armor. It has these yellow foam pads inside, and is similar to hold. It's technically 2 pieces but in the real world it appears very very similar to OtterBox if not better.

Virtually every single case has the same flaw though: there is a very bad soft spot in the case...every case....over the ring mode selector slider (silent\vibrate\ring). Some cases it's not quite as bad than others. But it's been present on every case I've tried except 2. And those cases fixed the issue by sandwiching the phone in between 2 hard pieces:

One was a heavy as hell all metal case that's a MONSTER in size and weight, and most people will hate, but does an incredible job protecting the phone. And it uses any old 3rd party glass screen protector. Your floor will be dented by falls, not your phone! (this is currently my case).

The other is the Supcase Unicorn Beetle Pro... an all plastic case that doesn't let you use a glass screen protector, you have to use their built in thin film screen protector that SUCKS and makes the case useless. It doesn't have the so called soft spot. But the lack of glass screen protector kills it for me.

It does come with a not so great belt holster though if anyone wants that.
