I guess I'd better ask this before Sonic Mania comes out and makes the answer too easy.
Personally, I'm partial to the Master System version of Sonic 1. It's a pleasant and well-designed platformer--a bit basic, but fun--with level design that feels more like Mario than Sonic. It's a nice casual game that I probably beat once a year.
