ROTS Darth Sidious >= ROTS Yoda = AOTC Yoda >= ROTS Mace Windu > Count Dooku = ROTS Anakin Skywalker = AOTC Mace Windu = TFU Galen Marek (Starkiller) >= ROTS Obi-Wan Kenobi = ROTJ Luke Skywalker >= OT Darth Vader >= TFU Shaak Ti = ANH Obi-Wan Kenobi >= ROTS Plo-Koon = AOTC Obi-Wan Kenobi >= ROTS General Grievous >= ROTS Kit Fisto = TPM Qui-Gon Jinn = TPM Darth Maul >= AOTC Anakin Skywalker >= TPM Obi-Wan Kenobi = ESB Luke Skywalker >= ROTS Ki-Adi Mundi
According to this chart:
ROTS Sidious vs ROTS Mundi - Sidious oneshots.
AOTC Yoda vs OT Vader - Yoda clearly wins, but Vader lands some good hits.
ROTS Obi-Wan vs TPM Obi-Wan - ROTS Obi-Wan STOMPS
Oh, and for the record, this isn't in the movies, but Luke Skywalker is said to become 2x as powerful as Sidious, so basically if he were included in the chart:
Prime Luke >>>>>>>>>>>>>>>>>>>> ROTS Sidious >= Yoda, etc.
