Christian: Catholic.
I was raised as a Southern Baptist until I was about six years old, as that was what my dad was raised as. He's not a very religious man, and only calls himself a Baptist because that's what he was raised as. And really the only reason I was raised Baptist was because the local Baptist church was the only one in the area at the time.
Then my family moved to a larger city and we began attending a United Methodist church, which is what my mom was raised as. She, like my dad, isn't very religious and we only attended that church because it was my mom that made us go, usually only on Easter and Christmas.
Then, when I was in college, I converted to Roman Catholicism. Virtually all of my friends from grade school through college were Catholic, so I got a good view of the Church.
Some people up-thread said they find traditionalist ways of worship to be boring. Well, I'm the exact opposite. That's exactly why I find the Catholic Church so appealing. The regimented structure of the service is really inspiring, IMO. I never really felt God's presence in a Protestant service (and I've been to quite a few besides Baptist and Methodist - Church of Christ, Disciples of Christ, Church of the Nazarene, Lutheran, Presbyterian, Episcopalian, etc.). But I do feel a sense of "other-worldliness" in a Catholic service.
Now, that being said. There are a lot of things I disagree with the Church on. I many ways, I'm a liberal Catholic - in that I'm a classically-liberal libertarian and supporter of the free market, which are things the Church isn't very comfortable with.
Also, as others have said, I think the most important thing is that denominations aren't that important. If something works for you, I say more power to you. If you're comfortable and happy being a Catholic, so be it. If you're comfortable and happy being a Protestant, Jew, Muslim, Hindu, Buddhist, atheist, or whatever, so be it.
