It's like everything else - if it works for you, use it. If not, don't. There have been plenty of races where I couldn't get the meta car to behave for me no matter what I did.
If I knew more about sim racing in general, I'd tell you that if you race it like [fill in the blank], then it excels. But if you try to race it like [fill in another blank], it won't cooperate. For me, it just works well with my overall style of racing. Lead foot on the gas and brakes, lots of praying and finger-crossing (makes using the wheel a challenge, but you do what you have to do!) and cursing. Especially the cursing.
