tbh, there will always be people who will hate GP4 and every mod and improvement that goes into it, likewise with F1C haters and will put down mods for it too just because it's.....well....F1C and then there's people who follow blindly although i hope that's a minority of both communities.
personally i feel RH's work is vital to the F1 part of F1C and good for them for building up such a huge fanbase but what people think is the best car just from a render and not seeing the actual car in-game or in zmodeler is a bit of a premature statement. for a fair comparison you really need to see how the cars look in the same program whilst also having to consider the fact that in zmodeler, the typical F1C car has a longer wheelbase than a typical GP4 F1 car that obviously will affect how it looks when compared
