Which is a better board game: Chess or Go?

Of the two, probably Go because it's easier to set up and modify. You can have Go games of several different sizes, and it can be drawn on paper if you need it to be. Though I also like the different variants of Chess that are not classic Chess. Not that it has never been hybridized; look up a game called Cho (have been asked to link in this manner, Google having more commonality I guess, questions didn't seem welcome).
