What is your favorite old school console?

The SNES has better versions of practically every great NES game you listed. Super Mario World/Super Mario RPG, Super Punch-Out!!, TMNT: Turtles in Time, Zelda: A Link to the Past, Super Metroid, Final Fantasy 3(6), etc. NES gets points for being groundbreaking, but as far as raw gameplay and enjoyability goes, the SNES wins hands down. If you put any of my examples here against the corresponding examples you listed, there's no contest for most of them (the only legit argument I could see would be with SMB3 vs SMW, but considering SMB3 is almost universally considered the best game for the NES, and SMW was average at best for the SNES...). The NES paved the way for the excellence that was the SNES.
