1.Sonic is a hedgehog. Sally is not. It is like a man dating a pig!
2.Sally is not in the games. Amy is.
3. (Sonic underground refrence) If sonic's mom is the queen of mobius, and sally's dad is the king of mobius doesn't that make them RELATED?!
4. Amy is in Sonic CD, Sonic Adventure 1&2, Sonic Heroes, Sonic 06,Sonic and Sega all stars racing(excluding iOS), Sonic Generations and Sonic X. Sally is only in SatAM and the comic.
5. In the games, there is no refrence to Sonally, but there are to Sonamy.
6. Half the fanbase does not know who sally is!
7.Sally uses Nicole for everything, as Sonic doesn't use nicole much.
8.In this club, there are more pictures of Sonamy than of Sonally
9. Sally is the only girl that is naked.
All in all, Amy is better for Sonic than Sally.
