Again, Frieza's returned was well received by the fans therefore it was well written.
Fan reception is by no means a sign of good writing quality when they tend to eat up whatever's thrown at them. If anything, it's the opposite in modern times.
He has a legit history with the Saiyans and Beerus which add more drama in the story which Cell hasn't other than he was just another threat to the Z fighters.
His role with the Saiyans was concluded with the Freeza Arc and his role in FnF was essentially just parading his corpse. As for Beerus, whilst that is true, their "history" results in nothing but Freeza's perpetual role as the Hakaishin's bitch and his fear towards him lead to nothing as far as the ToP goes.
Cell indeed doesn't have this and I wholeheartedly agree that he's nowhere near as effective a villain as Freeza. It's because of this very reason I'd prefer to see Cell in the ToP as I'd care far less about what little characterisation he has being damaged than Freeza getting ruined.
Frieza's returned made the arc compelling and interesting.
We already knew that whatever he did wouldn't matter due to the end of Z already assuring the continuation of the status-quo.
He has a reasons why he has to be one of the member of U7 while Cell doesn't.
Fighting strong people and proving his perfection isn't enough?
Freeza is arguably the most entertaining character in the ToP with him negotiating with other Universes, keeps teasing his betrayal and so on.
Which lead to nothing but trolling.
Toei made Freeza great again so that's enough.
I'd consider him messing about for over half the battle royale, losing all rationality against Toppo and being made out as a complete non-threat by the end the complete opposite of making him great.
