I like old timers. Kureha, Gan Fall, Woop Slap, Hyogoro. They are able to put things in perspective and draw in verse parallells between characters. A bit disappointed by Chinjao and Neptune, too little lore.
I’d rather see Shiki in an old state than Gaban but I’ll take who we get. If we get Shiki it would be interesting if his ”20 year plan” comes in to play somehow. He might not be stronger than Kaido but with 20 years of preparation and his terrain he might well be stronger under specific circumstances providing a perfect antagonist.
