Thunderbolt is also significantly juicier, as you can daisy-chain 10 or so stuff and still get pretty high speed anyway since it uses a better protocol. (within reason, of course)
I imagine eSata has lower latency ir something.
eSata is the same as if it was internal, as it is just cosmetically different from a normal Sata port on a mobo. Can run circles around USB 3.0 anytime, anywhere as it has a lot less overhead sot it is much closer to its theoretical max speed than USB 3.0.
USB 3.0 has power though, while eSata does not. (well there is eSata power that steals the power from a USB port, but it's rare)
