They both work well and fit me well...have medium size hands.
Biggest advantages to the CZ are magazine capacity (I run a 19 round in my CZ75B) and the DA which allows a second strike without recocking if there is a possible primer issue. The DA also makes (for me) dry firing easier as I don't need to cock the hammer or rack the slide (I use a firing pin activated laser).
Disadvantages are that unless you are good with really small parts
if you ever have to change something out it is a real pain. Even the trigger return spring can be a pain. Their use of roll pins also means that you must have a punch and spare pins if you're going to do much other than change the recoil spring. Lastly, the very small slide surface can make it hard to get a good grip for racking the slide if under stress.
On the 1911 I think that the safety is better, I like having a grip safety and it is fairly easy to work on...only a few small parts and unless you are fitting a part you don't need any special tools. The only downside (9mm) is the lower round capacity.
