That's what everything comes down to, especially in the non-professional shooters' gun world.
My personal preferences are mine, not anyone else's. I like what I like, and I have solid reasons for what I like. I don't think my choices are better than anyone else's, and I'm sure that there are those out there who make better choices than I do.
For instance...I love my bolt-action rifles. Love them to death. I love loading them one cartridge at a time, love slamming the bolt forward to pick up a round (have to slap the dog shit out of my M44 and my 91/30, but that's part of the experience), love the feel of the rifle snuggled into my shoulder, the feel of the trigger take-up, and the kick of the rifle. It's almost a ritual, for me, now. It's calming. And I need that, because it's one of two things that take the five separate trains of thought in my head (two of which are ADD) and get them all focused on the same thing. Makes things get quiet.
I know modern semi-auto rifles are just as accurate as (if not more so than) a good bolt-action. It honestly doesn't matter to me. I don't have a singe rifle that isn't capable of more than what I can do with it, especially after five years of little to now practice. My SAR is capable of almost as much accuracy as my husband's AR-15. I love the rifle, but I don't love it as much as I love my bolt rifles.
I am aware that wheel guns are more reliable, for the most part, than a semi-auto handgun. I don't care. Yes, they're pretty, but the angle of the grip, the feel of the gun in my hand, just isn't right. They're fine guns, but my personal preferences lie with my CZ-82...or my Colt 1903, both of which I'm quite capable with.
I do not like Glocks. I don't like that the sole safety is a DAO trigger, I don't like the angle of the grip, and I honestly prefer hammer-fired over striker-fired guns (and really like DA/SA...which is part of what explains why I prefer semi-autos over revolvers).
Personal taste. My guns are not better than yours, any more than yours are better than mine (unless you've spent a shit ton of money, and are a professional). I like mine. They're better for me, not better in general.
And I'm pretty sure your guns are the same to you.
