More than worth it for Assetto Corsa (OG & Competizione), rFactor 2 and Automobilista 2.
Automobilista 2 is my pick. Variety of vehicles and tracks is great and VR performance is unmatched. The physics have come a long way since a shaky release a while back and are now comparable to ACC & iRacing. Criminally underrated IMHO. You definitely want to keep an eye out for deals for the season pass or DLC packs though. There's a lot of extra content.
Assetto Corsa Competizione is also fantastic. It only does GT3 (& GT4) but it does it better than any others. VR performance is pathetic unfortunately. My 2D game of choice.
The original Assetto Corsa is brilliant for the infinite amount of community content. I'd recommend getting Content Manager and CSP.
iRacing is obviously the best for multiplayer, runs well in VR but an absolute money pit. At least with a 3 month trial you can race around an MX5 and get a taste before deciding to go broke buying extra cars & tracks.
Insane value.
