First... let me say that I am not trolling. I am not invested in eaither system as of yet and have been considering both. I have always used Canon G series P&S and really liked them...
I was just hoping that someone here might have used both and could give me some guidance. I reall want a 5DMII or MIII but I don't have the cash together as of yet.

Hold both cameras before you decide. If I had to choose I'd get the 60D. I am not invested in either system.
First, Nikon forces you into af-s lenses with the D5100. That is a big turn off for me. Not having the screw motor in the body and forcing me to purchase extremely expensive lenses, which af-s are except for a few, is a bad thing to me.
Second, I think you are not comparing cameras of the same class here. That's why I think you should hold them, read up on the differences, and you'll see the 60D is in a different class.
If you do not like to hold the camera you will not use it.
If this were the D7000, it'd be a different conversation.
EDIT: You should maybe be comparing it to the T3i.
