Which do you all think is the better deck type? The usual Cyber Dragon OTK or the Cyberdark decks?

Neither are very good. I guess Cyber Dragon OTK if I had to pick.

I don't think the 2 of them can even be compared, they have nothing in common except "Cyber" in their card names. A deck built around the Cyber Dragon fusions would consist mostly of machines, while the Cyberdarks need a dragon deck in order to work. However, the OTK potential is higher with the Cyber Dragon deck, mainly due to cards like Power Bond and Limiter Removal.

Yes, but what I am asking is which would hold it's own better in a duel? I'm going to take one or the other to a few tournaments.

both are equally good

As for as I'm concerned, a Cyberdark build would work quite well, since there exists the potential for sick combos involving Dragons. Not only that, but add in the right mix of Dragon-types like BEWD, REBD, Armed's, etc etc, and you could also put in Dragon Fusions for your opponent to sweat over as well as the Cyberdark Dragon.

Definately Cyberdarks.
