Might be Megadrive/Genesis for me as #1 as it stood well next to the SNES.
Dreamcast did have good games but maybe not as many quality titles of that generation that it could’ve had if it were around for another 1-2 years, and it lacked support from some developers because they jumped ship or ignored it, it was a proper next gen machine for its time though in terms of power, ignoring no dual sticks or more storage on the discs.
Master System had some quality titles even though it didn’t sell all that well worldwide compared to the NES.
