Love Chinese poker. Especially open face pineapple. It can be easier or harder...depends on how u play and what expectations are. Mostly it's harder because a much more complex game alll poker has elements of luck...its about the same in all games and is dependant on who is playing too so don't think of it that way.
I play both a ton...I like Chinese more than Texas Holden...but like Omaha hilo more than either.
It's hard to give exact skill vs luck ratios since it totally depends on the format you play. No limit can be 0 skill if you make the blinds 500/1000 and start everyone with 2 chips. You can bend the rules of any form of poker to have more or less skill required, and different skills required.
