Nintendo.
Actually, idk, when Nintendo wasn't king, i.e. PS1 and PS2 days, I was not buying consoles as I was neck high in school. I might have owned them had I had time/money to spend on console gaming. After all, during those days they had by far the best selection.
Granted I would have owned a N64/GC alongside so I could get Mario/Metroid/Zelda.
Typically though, I don't see myself owning more than one console and Nintendo has the titles (1st party) that I really like, so, Nintendo FTW.
