 If you liked Gakuen Heaven |  ...then you might like Princess Princess |
It's similar with the all boys acadamy and the transfer student thing. Princess Princess adds more of a comedy sense to the anime. In both animes most events are quite predictable,both animes leaves you wonder what happens after words. Hey now why not give it a chance ^^
Both series are set in all-boys schools with shounen ai elements. Both have beautiful art and interesting characters. Gakuen Heaven has more yaoi in it, but Princess Princess is better with comedy.

Both shounen-ai animes are about school life in an male-only boarding school. Whole lot of bishies (aka handsome drool-worthy young gentlemen) who makes it worth watching.
Both have cute boys, average art and not a lot of action.
