Hello!

1. Does anyone know the average range that could be covered with the modules nrf24l01 and esp8266 respectively?

Posts across the internet mention that the esp8266 is interesting but sufficient details about the range is not given.

Other stuff that I came to know about:
PROS (esp8266)

esp8266 can be used as a standalone node
esp8266 is cheaper than nrf24l01

CONS (esp8266)

esp8266 consumes more power than nrf24l01
esp8266 has only Chinese documentation that seems official where as nrf24l01 has better documentation and libraries ( such as for the arduino).

2. How far are these correct?

This product is not recommended for new designs. Nordic recommends its drop-in compatible nRF24L01+ or for a System-on-Chip solution the Nordic nRF24LE1 or nRF24LU1+.
The ...LU1+ is 0dBm for Tx
....
-94dBm RX sensitivity a 250kbps
-82dBm RX sensitivity at 2Mbps
-85dBm RX sensitivity at 1Mbps

Using high gain antenna and line of sight, using Friis Equations or online calc. , one can estimate distance for path loss assuming only Gaussian Noise and specified BER at threshold.
