Street Fighter Vs Mortal Kombat

Which of the two fighting franchises do you prefer most? I preferred SF likely because I liked the roster of characters from dhalsim to blanka.

I would say my favourite in the series is SF Alpha 3. Nice anime inspired gfx and mechanics.

Mortal Kombat I didn't mind but I wasn't a fan of the early 3D titles I.e. Deception because I didn't like their soul calibur like side step mechanic.

What are your thoughts?
