Shaolin is definitely more rewarding in most aspects of play. I'm not a Kung Jin player but I can definitely tell you that Shaolin is way stronger in footsies and rushdown. Ancestral has long start up gimmicks that involve zoning and there are too many characters that can punish him.
You know people who say Ancestral is bad, when they use them competitively (most recent hayatei) they get mopped lmfao. At least pig can make it to top 16 with kenshi all the way
If you're a takeda player Shaolin's gameplan would be easier to pick up. Ancestral is "almost" variationless jin so after getting used to Shaolin you would already know most of ancestral. Play shaolin and learn ancestral on the side.
Well sorry but you don't, and using a character from day 1 means nothing. You can have used a character since day 1 and still be shit with them, the same way you could've just picked up a character and be one of the best with them. I use both characters too and I know Ancestral is better than Kenshi is but I can actually explain why. But please, tell me why you think Ancestral is worse than Kenshi.
