The good thing about Buuhan is that he would make your Frieza a lot stronger, together they would get not only Buuhan's boost of ATK +25%, but also ATK & DEF +25% when HP is 80% or below, and HP +5%.

If you keep struggling you might want to try bringing him instead of Trunks, who can super at 9 Ki but isn't a hard hitter.
