Like Chevy vs Ford, there's really no one choice for CC, IMHO.
Personally, I carry a S&W Chiefs Special in .45. It's light, small and is a big bore. It conceals very well and after all, I'm not going to be target shooting with it.
I shot a Glock for the first time this past weekend and was very disappointed. I was hitting 10x rings with a Para LDA Carry but couldn't hit the target at all with the Glock. No offense to the Glock guys, but I'd never own one.
That said, I'm a Colt guy through and through but I carry a damned Smith... Go figure...
