Buckmark has done well for me
I've bought two Buckmarks -- a 5.5" Camper and a 4" MicroBull (which was coopted by my son). With a 3 MOA Millet Redot the Camper is plenty accurate out to 25 yards. I've shot Ruger Mk I and II, and find them satisfactorily accurate, too, but not as comfortable in my hand.
Hand feel is not to be underrated: I would call that a very strong factor when trying to choose between two guns of similar quality. You couldn't go wrong with either, really, so if one feels better, and points better, it probably IS better, for you.
(Not that it's on your list, and I don't want to derail anything, but my Sig-Hammerli Trailside is by far my favorite 22 of the dozen or so I've fired. It's also awesomely accurate; I've let quite a few others shoot it, and it always impresses. Cabela's still has some of these fine but discontinued handguns starting at under $400. The Trailside's only weak point is the stock trigger bar spring; a quality replacement is available for under $10.)
