Buying Rex Atmos for 2020?

Thinking about getting Rex Atmos for 2020, as I dont have 2024.

I am finding mixed reviews - so I wanted to ask you guys about it?

Do you guys like it? Worth it or? Does it make a big difference or "Will I be fine with standard MSFS".

I know that some say that I can just put a Nvidia filter on or Reshade. But those programs changes every part of the game - whereas as I understand Rex only the weather.
