that's true, think about which guitar you like the most.Just because some say a Wildkat is better for Rockabilly doesn't mean that a Sheraton cant do the trick.
I say play em both and decide. I think by the fact that you are asking, you are doubting your original choice of the Sheraton? just go with the one you like more.
If you really want to, you can even put a Seymour Duncan Phat Cat (p90 picked, sized to fit humbucker routing) and put it into a Sheraton at a later strage
