Up until 3.1 the lvl60 epic totem (+100 haste) was better than the WotLK one (+196 haste) due to an internal cooldown on the WotLK one but no internal cooldown on the +100 haste totem.
This has been "fixed" though by giving the +100haste an internal cooldown now and reducing the +196haste totem's internal cooldown from 45 to 30 seconds.

If you want a raw DPS totem quickly, get the +damage on LvB one from Venture coins. If you happen to have 25 Valor emblems, get Totem of Hex.
