Liked my CZ75b, thought I'd like the CZ97b... it is a decent pistol, liked the large size, but didn't like the ergonomics/balance of it... thought it was off (for me). Everyone who tried it at the range, loved it. It's a big pistol.
I much prefer my Sig P220 in 45. Everyone is different, best thing to do is to try someone's at the range.
