Snes Mini rgb modded has the best picture, but it does glitch a bit more than other models. For example I tried 2 SFC and 2 US SNES (one of each was a 1chip) on a PVM with Demon's Crest. On the SNES Mini there was graphical glitches on the top of the screen, but this was not present in the other 4 consoles I tested. I also tested all of them with Super Ghouls 'n Ghosts and they all have graphical glitches on the top of the screen. Having said this I'd rather the odd glitch with superior picture quality.
