Honestly I would ignore Jumborg Ace, Mirrorman and Redman, because Showa era heroes like that, didn't alway follow logic we today and in the Heisei era would except. It's like two different sets of physics, I don't want to hurt my head with.

Ace, going with his present self in modern shows and movies, he would destroy Heisei Godzilla, given how brutally strong he can be and some of his techniques like the Ultra Guillotine have cut through stronger things that Godzilla's hide. Taro, is even worse

As for Noa, just watch the end of Ultraman Nexus.

King?....King, the guy who made a planet size building, with his thoughts alone...? Nuff said.

Honestly, Big G's best bet is Ace. Doragory and Gomora...I would put my money on Godzilla. Though as a Choju, Doragory would do better than Gomora.
