IMO its all junk excetp the M-12, 870, older 37's and 31's
Karl Feltkamp, Kampfeild customs Karl, told me his father liked the Rem 31 the best of them all and I really think there is something to that......
All the guns you mention are top notch, BUT the Remington model 31 is, for me, the best of the best! The Winchester model 12 certainly has a wonderful astetic appeal as well, but for balance and "SLICK" flawless function the Remington 31 is slickest of all.
