I have had both wheels (new) and the Logitech Driving Force GT is by far a better wheel. It has a fantastic feel, its a thicker wheel, pedals are fantastic and the feedback is simply amazing.
I don't care how good you think the G25 is, the GT wheel is better and much cheaper. The G25 shifter is garbage and there is no point to manual in a computer game, it simply wastes time. Also when in sequential mode, the G25 had problems with TDU even though it was this game was designed to support it. I agree the pedals are better on the G25 but it really makes no difference.
The logitech GT is my favorite wheel by a long way, I bought 2 in case they stop making them and mine breaks.
I have owned the following wheels which were all bought new so you know what I am comparing them to.
- Original Logitech FF wheel what ever that was in about 1993
- Logitech MOMO F1
- Logitech MOMO Racing
- Logitech Driving Force Pro
- Logitech G25
- Logitech Driving Force GT (WINNER!!!)
Seriosuly, I paid $89 for mine (Australian) Bargain !
