Megatron and Quintessa are both the overall Big Bads. Megatron sought after the Allspark in the first film, assisted the Fallen in his plan in ROTF, partnered with Sentinel to accomplish his plan in DOTM, hijacked a KSI drone army in AOE, and was one half of the Big Bad Duumvirate in TLK.

Quintessa, meanwhile, was the employer Lockdown in AOE (Lockdown was working with, not for Harold Attinger) and, though she was in a Big Bad Duumvirate with Megatron, was the driving force behind most of the plot in TLK. Plus she looks set to appear in Transformers 6.

This leaves The Fallen, Unicron and the other Creators in a Bigger Bad Ensemble. The Fallen for being the true founder of the Decepticons, Unicron for being the Transformers' oldest enemy, and the other Creators for staying in the background while Quintessa acts as The Heavy for them.
