These are the clear ones to me for many of the reasons listed
top 3 in order
-NES
-PS1
-OG Xbox (also considered 360 and Dreamcast in this "modern online gaming" spot)
Basically the debut console of each manufacturer are the trailblazers with better follow ups that kept their vision going. I had to show love to DC though Sega was always ahead of its time, can't forget the classic NFL2k online sessions (4 vs 4 online co op as well!).
