I guess I would go for the Glock. I have had a good experience with them and they have been very reliable.
However, the other pistols are good as well. As you see from the responses, there is a variability in preference. Everyone is a little different.
So, my advice is to make sure you get to shoot all of the pistols you are considering. Many ranges have rental pistols and you should take them up on that.
I have been very lucky. I worked for a big aluminum kite manufacturer in Seattle with a lot of shooters. We would meet at the range for lunch and bring our pistols (some brought 4). We would get to shoot each other's gun and that gave me a great opportunity to try out a LOT of other pistols.
A gun which works well for one person might not work well for you. You need to figure this out for yourself. Making a decision on which gun to buy based on verbal input from others is like buying shoes over the internet. You won't really know what you got until you get it.
