It really depends on how much you're going to be hunting in conditions that require gaiters.
OR Crocs have worked fine for me over the years, but needed replacement regularly. If you are just going for a week or something, on sale at $50 they seem like a good match.
Ditto for Kuiu, Kryptek, Kenetrek, etc. My hunting buddies and I have tore through a pile of them.
They all do a decent job for a hunt. Even for a season. Maybe two seasons if you have some gear aid patches.
But if you are the type of hunter that spends months every year in gaiters and want something to last much, much longer in tough conditions it will cost you a little extra in both cash and weight:
