Lipo or LiFePo4 batteries

Hello all,

I am deciding a power source for a project based on ESP8266 NodeMCU. The ESP8266 has a nominal voltage of 3.3V and max of around 3.6V I believe.
Would you rather power it using a 3.7V 2500mAh Lipo battery via the Vin which would then require the onboard regulator (which I have heard is a wastage of energy) or would you choose a 3.2V 6000mAh LiFePo4 battery which can directly power the ESP8266 using the 3.3V pin without using the onboard voltage regulator?
Factors to be considered: ease of recharging? longer battery life?

Thank you in advance :)
