If you want to compare Zappa's talent to any "classical" composer talent, I'd put Zappa at the same level of Corelli or Schoenberg. Of course, these composers are not at the same level of Mozart or Bach (in terms of genius), but their music for sure will be played in some classical concerts from time to time, as now is the case of Zappa.
As I write this I'm enjoying "Hot Rats" album. Long live Zappa!
