Mainly INT Angel Golden Frieza (he has a farmable super attack rn) (if you do the first Universe Survival Saga Story event on one of the stages you can get a STR SR Angel Frieza that awakens into a ExtremeSTR SSR Angel Golden Frieza, which can give Angel Golden Frieza a 100% rate for a SA level up.

Other then him I also reccomend PHY Super Vegito (no farmable super attack), TEQ SS3 Angel Goku (he does have a farmable super but it is such a long grind it isn't even worth doing), INT Kid Buu and SSJ4 Goku.
