Yeah - the buckles are only hard to undo if you try to remove them right after you tighten them. After you get in for a few minutes, it's loose enough to undo pretty easily.

I haven't had any slippage with the rings, and I don't have to worry at all about not being able to loosen it if I want to change sites or something.

Six of one, half-dozen of the other...I'd say they both work fine.
