I didn't fully appreciate Kevin until he left and came back. Now he would probably be my #3 after Brian and Nick, as far as who I watch in concerts and who I want to stand by at VIP and that sort of thing. I agree with what you said about him, Tracy - he seems a lot more laidback now than he did before he left, and he's got a great sense of humor. I think it was harder for his real personality to show in the early days because he was always in the background, and the others stole the spotlight, not just on stage but also in interviews and stuff. Kevin likes to talk, but he was never the one goofing around like Brian, Nick, and AJ.
Howie has grown on me a lot in the last few years as well. And I agree about AJ being super nice. I know they're all supposed to be nice at meet and greets, and I've never experienced any of them being "not nice," but I will say, having met them quite a few times, AJ, Howie, and Kevin have always seemed the most personable to me. I don't know if that's just my perception because Nick and Brian make me more nervous because they're the ones I'm attracted to, or if it's true, but those three always seem genuinely happy to meet you. Not that the other two aren't, but I feel like it varies with them.
