This question isn't really about quality. It is more about type. If you like the longbow, go Centaur. If you like the recurve, go Zipper.
Both have an Excellent reputation. Both are well crafted. Both are proven to perform.
That said, I have to agree with someone above that stated don't get rid of a proven winner in order to purchase something you may or may not like. Instead, be patient...save the money a little every payday...and get on the waiting list. That would be my advice. If that is too pricy, there will always be another used bow around.
