Club championship of the CIS countries.

I would participate too, but I'm for TE :)

SoD is a good version, it's popular. For fun, offline, extreme, and pleasant emotions - it's up to everyone and what they prefer.

But for a tournament, in a club, TE is much more suitable. Randomness plays a smaller role in determining the result. In SoD, a weaker player has many more chances to win than in TE! If we are organizing a serious tournament, then TE. But if we just want to drink beer and hang out, then SoD is fine. IMHO, of course :)
