What's your favourite console/system for playing Sonic?

PC. Emulates Genesis, Wii, Cube, Cast, Saturn, etc. Multiple filtering options. Makes all the games look better than on the original hardware. Any controller configuration I want (Classic Controller Pro is my choice atm). Everything except hardware is free...etc

 

Original hardware, although I use an emulator more often now (I play a lot of hacks now and I don't have a flash cart, so yeah). Occasionally I'll hook up my old Genesis for some old-school fun though.
