Beam has the best driving physics hands down over any other car sim in most situations. Where beam fails compared to gt7 is high downforce high grip cars such as race cars, and crazy Super/hyper cars like the scintilla. Beams high downforce aero simulation sucks and its racing slicks and Super high grip street tire physics(scintilla) suck. The reason racing simulation youtubers struggle with beam is cause they always drive the race cars which beam doesn't simulate well and most times are tuned poorly. Beam simulates normal road going cars and sports cars the best. So if your into GT3 racing or race cars in general Gran turismo is better.
