Track drops for street riding is generally pretty silly. They have a very small flat section on top meaning you're going to have to grip them right at the stem. The bends are typically severe meaning they aren't that comfortable to grip if you want leverage without going into the drops. The drops are typically deep which limits your vision.
Probably the best setup would be road drops with brake/dummy hoods. You get the most hand positions that way. Bullhorns are a pretty close second (and in some ways are better).
I hated track drops so much that I don't even use them at the track anymore. I use Nitto RB 115 (road drops). I might try some shallow track drops in the future (like the Nitto B125s) but my experience with the Nitto B123s and the Deda Pista bars have been overall negative. They just aren't comfortable.
Ultimately, use what works for you.
