I'd say it's probably my favorite edition overall. I like things about all the versions of D&D I've played, but 5e hits the sweetspot for me. Other systems I've had experience with don't usually grab me in the same way D&D does, even if they're mechanically solid. I suspect a good setting with a system tied into it would give 5e a run for its money, but I'll admit my experience there is pretty limited. So I'd say I love 5e as much as I can love a system of game rules with some loose setting expectations.
