Chess or GO

I have played Chess for 40 years + and I love the game. A couple of years ago I took up GO and I love it too. Go is more complex than Chess in my opinion, but both games give back a lot. I've never had a Chess coach, but I have a GO coach and that might be why GO is so appealing. Frita, Rybka and the like can play GM level Chess, but no computer can play 9dan level GO. Not even close. Comments ?
