It has more to do with the sail plan than the similarities or differences between boats. Of course the sail's foils should interact properly with the keel's foil. And the keel's ability to work will also depend on the hull desiogn and weight of the keel. They're all interconnected and mean little when considered seperately.
A taller mast and it's resultant taller main will be desirable in lighter airs. There is better wind flow higher off the water and if the wind is light it may be profitable to have a tall mast. Of course you should be prepared to reef the mainsail a bit earlier on the other end of things.
The differences shouldn't mean a lot to you as long as you can easily achieve a balanced sail plan, thereby sailing effectively and fast.
