As long as the PC port is done well enough and you have a decent controller, fighting games on the PC is just fine.
I used to play several fighting games on the PC a long time ago with my Sidewinder and it was good. Even better now with my xbox 360 controller.
I play the arcade MAME versions of Mortal Kombat 1, 2 and 3 all the time. I also have a few of the PC ports of various MK games. Mortal Kombat 4 for the PC was the best home port. It was closer to the arcade than any of the consoles they ported to and as long as you had a good controller it was great.
