First, it's your money so buy what you want but I will mention a few things IMHO of course.
The argument hat m&ps are just as reliable isn't valid IMO. The m&p has not proven itself. I always post this link when this question comes up. Show me anything remotely like this done with an m&p.

Second the whole "buy whatever feels better" is also not a good argument for one over the other. Ak47, very reliable, they don't make them to feel good when you hold them. When I was teaching basic training all my soldiers got c7s. From 5 foot tall females to 6 foot 5" tall males. They all got the same weapon and all shot them just fine. 5 foot tall 18 year old female from nfld got top shot on the last course I taught.
Third, what is your criteria for purchasing a firearm? And what do you want it for? Do you want something that is a perfect fit for you hand? Some awesome 22s out there for that. Something to take to the range now and then to shoot? They will all do that. A gun for ipsc/idpa? Cz/glock/m&p etc.
For me personally the criteria that was the most important for me in buying a plastic wonder pistol was utmost reliability. It must go bang every time. No we can't ccw, my life doesn't depend on it but that's what I wanted. The bonus of it always working when playing ipsc is just that, a bonus. There is no other pistol on the planet that is as reliable as a glock. No other pistol can be put through the crap a glock can and still work. This is fact. That's really all there is to it.
If reliability isn't your main concern but rather how a gun feels then go buy what feels best for you.
I am also not some glock nut. I enjoy many handguns but you can be sure that my glock will work long after my 1911 quit.
