I would never buy BT over Hydra on a melee over Hydra except maybe on Riven, but even then, Hydra gives more burst for Riven and she doesn't have to worry so much about dying.

The build path is one if the biggest reasons to build Hydra over BT. Tiamat is only 350 gold more expensive than BF and only gives 5 AD less and you actually get stats out of your gold on the way by it being made up of 4 items and that doesn't even touch on the whole waveclear + more damage in trades. Also, the 15 hp/5 shouldn't be overlooked either, even if it isn't a "combat stat."
