I mean, some would argue DC is superior anyway. Not me, but don't sell your nerd cred short yet!
I actually enjoyed GoG2 more than most. I thought it was just as good as the first one, with my only real complaint being that it felt they leaned a bit too hard on Drax being comic relief. In the first one, he was this ultra serious character that didn't realize how silly he sounded at times. In the sequel, you could tell they wrote it with the idea of him being the funny one, and it just kind of changed the character for me.
Overall, I still really enjoyed it, but I also haven't seen it since I was back in theaters, so opinions could be different on a rewatch.
