There are many high school gyms in the area that are way better than the JAR.
Really, besides Barberton I can't think of any. I suppose you will have to define "way better."
Barberton is tiny for their school size and ungodly sterile (it's mostly grey, with some purple trim), from what I recall from regionals in HS.
The only thing that made it seem cool back then was they had a hanging scoreboard and hoops that actually were freestanding.
