Most of the hard core flyers seem to prefer Liftoff or Velocidrone. I can not comment on DRL as it requires Windows 10 and I am staying with Win 7 for as long as I can.
Worlds Adrift was created from a game and not sure how realistic it is.
My favorite sim is FPV Freerider Recharged.
There is a new sim in development and is currently free through a Steam account. Orqa FPV SkyDive. They make a pretty nice goggle so I have high hopes for that one.
There is also another newer sim on Steam called DCL The Game. I have been waiting to hear from others how good it is before spending the money on it.
Out of the three you mentioned I think most would go for Liftoff...
