I prefer Kristen/Kristin. I've known a lot more of them and so the one
Kirsten I've met seems backwards to me. Plus
Kirsten seems a little snobby. Like when
Anna wants you to pronounce it Aw-na. Yeah, I do find
Kristen kind of boring. I've known 6, plus it's similar to
Krista and
Kristine, so I end up lumping them together in my head, which makes it feel like even more.
