I will add for those who haven't tried these, as it usually doesn't come across in verbal comparisons:

Digital FPV (like DJI's system) looks vastly better than analog. I think the best comparison is: Digital looks like a modern movie, youtube video etc, and analog looks like CCTV footage from the 80s.

I will also clarify on ELRS: It uses ESP32, but it is a thin wrapper around Semtech LoRa (~915Mhz and 2.4Ghz) SX128x and SX126x chips, which are doing the heavy lifting.

I heard people flying analog also use quite a bit more transmitter power than allowed for non-regulated devices to keep things manageable. Do you have any reference what's possible with digital when staying in the allowed regime?

The bigger advantage with analog is being able to use cheap repeaters to boost the signal back to home.

With digital, you can go from 30-50km with the proper equipment, noise free environment etc... It looks like the video for that has been taken down. But you can find the discussion here: https://greyarro.ws/t/digital-fpv-dji-vs-hdzero-vs-orqa-vs-w...

The "allowed regime" also differs based on where you live. Iirc 25 mW is the maximum permitted power in Europe. Have to double check. That gives you about 100-500 meter range in an open area.

A big advantage with digital video in the US is that some systems, like DJI’s, have FCC approval and can go up to 1 or 2W EIRP legally, so the allowed regime is bigger (there are basically no FCC approved analog video systems, so really you need an amateur radio license and to operate under amateur radio rules for analog video in the US).
