Need a new Handgun

I've been contemplating the purchase of a new handgun for months. Right now my main full size is a Ruger P89, love it. Built like a tank and will eat anything. My EDC is a Ruger LC9. Great little gun and accurate enough. Eats everything I've put through it so far. Bought a S&W SD40 VE last fall and have been trying to like the 40cal, but just haven't fell in love with it yet. Since my wife doesn't like shooting the 40, I'm looking for a strike fired 9. I've debated several guns and am now down to the S&W M&P 9 or a Glock. I hate online reviews because people skew them to their own likes and dislikes. I'm torn now as to whether it's time to just get a Glock and not look back, or get the S&W. If anyone has either a Glock or S&W M&P 9, I'd like to hear your thoughts. I don't know much about the Glocks and the different flavors they offer. Thanks.
