It's right that 433 will have much better range. but I'm receiving constantly float data at like 100kbPS. And I dont like big antenna, at present 10 meters is already acceptable for me.

take a look at 8266:

it seems that all depends on the TX power(nrf24 fake one have 4dBm while 8266 can reach up to 20dBm).

But, at full power, the ESP8266 can easily draw 650mA - 800mA ....

Yep

Wifi has far more range than nRF24, because it transmits with far more power.

You could also take a look at LoRa modules, albeit more expensive, as they amazing range and are very low power

Some range comparisons:

This guy has gotten some ridiculously long distance communications with nrf modules (up to 14km with external yagi antennas).
