I have a Fanatec GT3RS Clubsport wheel. Personally, it's better than the G25. My G25 shifter broke, it wouldn't select some gears unless i tried a few times. The Fanatec comes with 2 sticks, so it gets round the problem of the shifter being flimsy. The Gated Shifter for the GT3RS feels meaty to use, has quite a bit of ressistance. The Sequential is rather good too, with no sideways play like the one on the G25.
The wheel itself feels overal better, with a nice racecar feel due to an Alcantara fabric on it. It has a nice "D-Pad" and 2 buttons on the bottom spoke, with 4 more buttons at "3 and 9 o'clock".
The pedals are weel built. Beautifully machines and put together. The brakes have a potentiometer wich is adjustable. So the harder you press on it, the harder the brakes come on. This is adjustable though, as is all the positioning on all the pedals.
The only downsides i've found is that the wheel does get rather hot after a short time of playing, and that the Alcantara does slightly galze over with moisture after a while. But other than them little problems, it's the best wheel i've had.
Hope this helps :)
