Well, aside from cost, not too much difference, you do have to pay out extra to get them blued, parkerized or whathaveyou. I like stainless better, it's more tolerant of my lazy ways.
I DO note, that most benchrest shooters are using stainless barrels, though, and those guys don't mess around when going for the bestest/mostest for accuracy, etc.
Like anyone else, I'd rather look at nice bluing and pretty wood, but stainless sure has some advantages, though probably not in accuracy when the tube is new.
Complicated, isn't it?
