Long version:
You know, I play Raceroom more than I used to a year ago and enjoy that fact that they've updated the physics of some cars to the newest model, AI has improved and they've added multi-class. All great.
However, no day/night transitions, no dynamic weather, fixed tire pressure, no real road tech - these are the things from top of my head that people have been asking for quiet a while, yet we don't even know if any of it is in the pipeline. You claim that it's best in the business, and at the same time people complain that all S3Studios does is release new content while not fixing core issues. Check out the forums what people think of new ADAC GT Masters 2018.
rFactor2 has seen lots of improvements since S397 took over, but there are some outstanding issues and not everyone is pleased.
You see the analogy here?
Either the teams are too small, or the issues are not that easy to fix. How can one criticize one developer and praise the other while clearly both struggle to deliver
all at once what people want?
I see improvements coming both from Sector3Studios and S397 and I'm grateful. Rome wasn't built in a day either. The thing is, neither rF2 nor R3E are at the end of the life cycle. Luckily we can expect improvements from both titles, but not everything is going to be fixed today. Yeah, I get it. We want everything here and now, but be a little more realistic.
Short version:
No sim is perfect - pick your poison. If at this time you are most pleased with Raceroom - go enjoy it, here and now. Come back to rF2 in a while, maybe things will be to your liking then. We have options
