I went with the M&P in 40S&W, I love it. I've fired various Glocks, including my brother's G22, and I always felt like I had to twist my wrist up at a weird angle to get the sights on target, and even then I really couldn't hit very much. I don't know if that makes any sense, just felt weird to me. The M&P points very naturally for me. Sights are right there as soon as I bring it up, the grip feels great. Apex trigger upgrade is must IMHO, one drawback.
I don't dislike Glocks, in fact I would like to get one still, I'm sure with more practice I can be just fine with a Glock. But for a new shooter I think you would like the M&P better, just because of the grip and better sights.
