EthBotdZerk VRS EthBotdCB

...botd CB, no question about it.

Range, it's all about the range.

He's not asking the best all around weapon for many chars (no other char can really make good use of a botd CB except for maybe a poor druid), he's asking the best for a Bab, and I'd have to say BOTD CB is much better, and much more damage 2 handed (against a sorc or some such)
