It’s going to boil down to do you care to have the bottom open or not? If not, then I’d go Bullstrap no question. While you will pay a little more, you’re getting the lifetime warranty. Using promo APPLEWORLDFAMILY which I assume still works will save 15%. The buttons are also better on the Bullstrap in my experience. I also don’t like the metal camera bump wrap on the Andar unless it’s the jet black which sort of hides it. That is of course personal preference. You really can’t go wrong with either but I’d lean BS if having the bottom open was not a big deal.
