I had a YZ2 and it was fast but hard work so ditched it. Bought a KF2 and it seems easier to drive, not as fast over a lap but faster over 5 minutes. The SE edition KF2 is better as you get all 3 layouts in one box. It takes very little time to change it as well.
The PR S1 V3 looks like a bargain, £240. The spec looks excellent not sure about the quality as I've never seen one.
The "my car is better than your car" opinions are BS and as for manufacture bashing that's pathetic. Every manufacturer has their issues, not one is perfect.
At the end of the day different cars suit different people. Go to a club and try each car and see what suits you. Like it and buy it.
