Alien 3 is definitely a better film than AvP Requiem. I just get more light-hearted entertainment out of Requiem.
I'm a big fan of Wolf's design (with his mask) and I appreciate that the Bros tried to portray him as an elite hunter, despite their flawed execution. Also...some scenes are unintentionally hilarious, and I get a kick out of those.
I find Predator 2 more re-watchable than Aliens...and of course, the latter has more critical merit.
