I don’t think any console racer has come close to the ease of finding good, clean racing quite like GT Sport has. I think it’s a revolutionary concept to introduce to consoles from pc sims like Iracing.
May not have the most content, but content doesn’t mean good racing, case and point Assetto Corsa Competizione.
It’s by far the most accessible, the fastest to get racing, decently balanced in the Gr.3/4 classes and it has a good selection of exclusive tracks you can’t find elsewhere. Therefore it gets my vote.
