I know that it probably doesn't matter whether it has a rotating hammer or a straightline striker, but perceptions matter. I've played with both and have come back to preferring hammers. Having disposed of my Glock and xD, the only striker fired pistols I still own are a Colt .22 Target Model and CZ 100. I feel safer with a hammer equipped pistol. I know that's not true, but again, perceptions count for something.
The only thing left for me to do with my other pistols is to get spur hammers installed on my S&W 908 and 6906. Raised on D/A P-38s and Model 39s, I like to hold the hammer with my thumb as I use the decock lever. Every time I see those hammers fall, EEK! Yes, I know it's safe. No, I still don't like it.
