Vitor, calm down. Comparing Chess to other games is on topic in a general Chess discussion forum.
As for the original topic, I think comparing Go and Chess based on statistics is just silly. The game play is completely different, so it's all a matter of taste. Statistics are irrelevant.
Now comparing Chess and XiangQi based on this type of analysis kinda makes sense, since they're similar games. Fans of XiangQi try to argue that it's the better games, since there's more types of pieces (7 instead of 6), it's played on a 9x10 board instead of 8x8, and there are less draws.
But there's a major factor that they always forget to mention: pawn structure. "Pawns are the soul of Chess", but in XiangQi, they're just a weak attacking piece. They don't protect each other and form pawn chains in XiangQi like they do in Chess, nor do they promote to powerful pieces when they reach their maximum potential on the opponent's back rank. There are also less of them. Thus, in Chess terms, all XiangQi games are open, tactical games, rather than closed games.
So for those who like attacking and tactics, this makes XiangQi the more exciting game. For those who prefer positional subtlety, Chess is superior.
I think XiangQi is more fun as a game, and I'd probably play it a lot more if I had the opportunity to do so. But there are no clubs anywhere near me, and very few internet sites in English, not to mention very little in the way of improvement books published in English. So I stick to Chess, until I get sick of losing, then switch to XiangQi for a while.
