Because in ECL logic Transistors doesn't go to saturation region hence saving the recovery time and making this family the faster.
ECL or emitter coupled logic is faster than TTL type logic because the switching transistors do NOT go into saturation in either the on or off state. The switching time from saturation in a high output to saturation in a low state like TTL requires that the junction capacitance be overcome and that the charge in the saturated junction get swept out. ECL is sensitive to a threshold level only.

Transistor Transistor Logic. Main feature is cheap and old technology. Drawbacks it has limited speed and fan IN-OUT.

I believe you mean low power, not low energy.TTL is typically lower power than ECL, but not always. Some TTL devices have been higher power than similar ECL devices.

ECL
In electronics, emitter-coupled logic, or ECL, is a logic family in which current is steered through bipolar transistors to prevent saturation.
The main advantage of ECL over TTL is speed.
