1. Raonic's serve is as good as Inser's, if not better. Just look at last year's stats on service (1st % won, fastest serve, % games hold, 2nd serve won %, etc.)
2. Federer has had no problem dealing with Isner's serve in the past, so your statement doesn't stand true.
3. Raonic has put Feder into trouble more than Isner has with his serve (look at the match between Fed and Raonic in Madrid, Halle, and Indian Wells. That's three different surfaces clay, grass, and hard court), so I would say Raonic's serve is more effective especially against top players like Federer.
