I run a full clone team and Sarge is pretty legit when you have him 7* and geared / leveled up. His middle of the road on his own but in a Clone squad...noticeable change in dmg and utility. My opinion is that clone synergy is better than any other outside of Ewok.
Anakin is pretty good if you don't have Rex for a squad lead. I do recommend swapping in Ahsoka instead of Daka. You'll make the most of Anakin's leader ability and she is a very solid character. Excellent damage, good survivability with her self heal, and clutch team heal ability.
