We could to and fro forever on CSR, GT3, etc. vs G27, but again, it's all about preferences. Our trusted

Force feedback fade is the often unrecognised villain. On some wheels it can take less than 10 minutes of use for the ffb to become limp compared to what it should be. I own a DFGT, a couple of Porsche wheels, and an ECCI 7000. They range in value from $100 right up to $3000 for the ECCI, but I can have a great time using each of them. One big difference though is that only one will feel the same after two hours as it felt in the first minute. No prizes for guessing which one.
We've got too much off topic material here though, so we should move over to the hardware section or stop.
