I have both F1 2019 and GT sport, I get a lot more hours out of GT sport. F1 is great for campaign but the game is unplayable for online, while GT sport has an awesome online system with different championships going on all the time as well as daily races.
I say it’s a good call to learn on F1, do a season of the career mode and then dive into GT sport once you are comfortable with the rig. I’m unfortunately still just on game pad
When you do get gt sport add me jklupul
