As bmcgilvray pointed out, revolvers were originally called "revolving pistols"-- to distinguish them from single shot muzzleloading pistols, which were simply knows as "pistols". If I picked from the pistols/revolvers I currently have, I'd have to go with the second pistol I ever purchased and one I still own: a 6" 686-1. Reliable as the day is long, accurate, versitile because it will handle .38 wadcutters through hot .357 mags. My 6" 686 is the replacement for a 4" 686 that was stolen from our house 25 years ago. I have a 25 year history with that 6" so I guess I'm just familiar with it and have confidence in it.
I've found the 6" works well as a house gun, a holstered sidearm around our property, and for hunting. Yes, CCW is difficult and a 4" RB K frame, a J frame, or even a 1911 is handier to carry, but I am more concerned about protection around the house or property than I am about the street. Plus I don't think I'll ever have to worry about a "cylinder capacity limit" and having to get a cylinder with two charge holes permanently blocked off to reduce capacity to 4 !!
A close second choice- or if I would buy a pistol specifically as an only handgun-- is a 4" K or L frame .357. The same positives and it's just easier to carry
