Having owned or own most of those on your list, (except the Browning 150) It comes down to a revolver or auto. Which do you prefer? All of them are "premium" models. Parts for the most part are available for all. The Colt OMM has the old style lock work, and if work is needed not that many gunsmiths are available for them, and some parts hard to find. The auto's will prefer SV ammo for the most part. The revolvers don't really care, but most likely more accurate with SV ammo. For myself I prefer the S&W K22 Masterpiece over the Colt OMM, and the High Standard Supermatic over the S&W Model 41. 22's are notorious for being unique to themselves, and finicky about ammo.
