Yes, Madara and Sasuke were the only ones with EMS. But Sasuke was both empowered by a 9 Tails chakra and by Jugo's curse Seal, yet was unable to cast Perfect Susanoo.

We only have statements to go by with PS for Madara. Madara notes that no one has ever seen his Perfect Susanoo and lived to tell of it besides Hashirama. That means he had to have used it in life.

If the Tailed Beast were unleashed, Tsukuyomi would affect whoever was in control at the time most likely.
