I'm in the market very soon.
The 15H has 2-3 dB more output than the Empire from 20-40 hz. Below and above that range the Empire has more output.
The 15H is considerably larger than the Empire. The Empire's prodigious midbass capabilities and dual opposed sealed design gives it a considerable advantage for music. It also allows it to be crossed over at much higher frequencies if one needs to integrate with smaller satellites/planars.
Each has its own strengths and compromises.
If you don't mind a larger sub and need to fill a large space for movies around $1K get the 15H. If you need a smaller sub, prefer the "sealed sound" or want a sub with extremely high output for music get an Empire.
Both are versatile. The 15H may have an advantage for movies bit is still musical. The Empire may have an advantage for music but is still excellent for movies.
There is no clear cut winner just differences to accommodate various preferences or needs.
morrischestnut's response is the most common reason to choose between subs in the same price range.
Good luck with your search.
PS: If you're definitely going ported and can stretch the budget the Rythmik FV15HP is a performance per dollar monster.
