What are you thoughts?

If the number of GPIOs, free ADC-inputs or other hardware-requirements are no problem, then use the ESP directly.

As already mentioned by Mmiscool : In this case you may use the Arduino API. LUA would not have a reasonable benefit, if you are already comfortable with the Arduino API.

Benefit of the espressiv SDK API: New features and bug fixes are available earlier and you need less RAM/ROM.

If there are other hardware-requirements: Do not use the built in AT-commands. Write your own ESP-software and connect the other MCU via RS232 or SPI. Cou can choose a baud rate, that fits to the other MCU witout "baud rate crystal".
