WotU (397) =~ BW (397) if (and only if) it is used to both a) reach 3202 haste and b) you can synch up AA/t134p with it during the fight. Even then, the trinkets are just "relatively equal", and I personally wouldn't replace WotU for BW unless it was an unusually grindy glass night and I was just "experimenting".
In all other circumstances, Cotc + WotU should be default.
Also keep in mind, if you're doing 95% of your potential dps, the extra 5% will rarely be what wins a fight. I find that most of the time when my guild finally beats a fight, we bowl the fight over or we fail epically. There are very few marginal wins, except for perhaps first kills. Basically... I wouldn't obsess about the trinkets so much...
