As far as religions go, I think Christianity is fairly boring. The moral teachings are nice, but my understanding is that Jesus didn't say anything someone else hadn't said already. There's only one god, and one that's pretty nondescript: He's supposed to be omnipotent and benevolent and that's pretty much it. He doesn't even do much: Sure, Jesus did some miracles, but healing and providing for basic needs are pretty unimaginative. Bonus points for resurrections(didn't Jesus raise some other guy from death?). Old testament is better, but then it's stolen from the jews.
I think Buddhism and Hinduism are the most interesting of the major religions, but that's probably at least partially because I haven't had any contact with people of said religions. Buddhism because there's no god(atheist religion is, at least for me, somewhat interesting as a concept) and because it seems to actually succeed in encouraging people to be nice(see previous sentence) and Hinduism because there's gods who actually do interesting things in the mythology and because polytheism is just more interesting than monotheism.
