well since this is only opinions, there is no wrong answer...
I much prefer polished stainless... I have several satin / bead blast finished stainless guns, & if I get holster wear, or a light scratch, I find it's better to leave it alone, rather than try to "fix" it... I've found it difficult to exactly match the factory satin finish, & often end up with a bigger "spot" of unmatched finish... with the polished stainless, a little Flitz, & you can't tell after a light rub down...
after that, & since everything can't be shiny silver ( that would be boring ) I like high polish blued...
the black "coated" stuff in flat black is probably next, but I have a lil air weight J frame that I dropped a couple times, right after I bought it, before I got a good holster for it ( trust me, leave those cheap nylon holsters alone
) combination of the softer scandium frame, & the "painted" finish turned that one ugly really fast... the cylinder is steel, & has nary a mark, but the soft frame has much silver exposed
