No the ESP32 uses less power. In deep sleep it uses about a quarter of the current. It also has an extra low power processor (ULP) core than can run in a sleep state and do IO without even waking up the Tensalica cores. The ESP32-S2 actually has a Risk-V core that runs as a ULP. As I said, it's better in every way.
