I think the two vote-getters so far are obvious...
But I think Wisconsin has it easier. They could get there completely missing OSU, if they don't have OSU as a crossover and UM or PSU beats OSU, and then they just have to get by one of those two teams in the CCG.
Florida is in a tougher conference, and I think that whatever team comes out of the West into the CCG is likely to be favored over Florida in a CCG and a harder team to beat.
That said... I think Florida has a talent advantage on Wisconsin, and if they made it to the CFP, would have better odds at winning the NC than Wisconsin would in that same situation.
