If I really had to choose between Saberon and Saurok? Yeah.
Saurok have more stuff.
Flesh shaping, dinomancing, they seem to wield magic (especially water) and are able rogues, they are able to form Warbands, they seem to be better at organizing themselves as we see numerous different tribes of Saurok all over Pandaria.
All that said, I wouldn't choose either to become an Allied race. They don't seem to fit anywhere
