The number of "ways" in a speaker doesn't really have anything in common with the issue of whether or not to use a center channel.
Both can be complex subjects, with there being exceptions to any general rules of thumb we might come up with. The short answer in either case is, "it depends on the application".
I'd say the ideal center channel speaker is one that's identical to the left and right main speakers, with all three positioned behind an acoustically transparent screen.
As for two way vs. three way, in my opinion there are other factors that are much more important to consider. There are excellent examples of both types, though a particular application may be in general more suited to one type than another.
