The Logitech G29 gets you higher-end extras at no extra cost. Its pedal board is much better than anything else at the price too, with a board that has a clutch and very solid metal plates. It’s not plastic rubbish.
There is one reason to prefer a Thrustmaster wheel, though. The Logitech wheels still use a completely gear-based system for their force feedback rather than belts. While it’s very powerful, you can feel this geared effect as you turn the wheel, as its motion is a bit notchy rather than completely smooth.
After a while you get used to it, but it makes the whole experience that bit less realistic; unless you drive a Flintstone’s era car it shouldn’t feel notchy, right?
The Logitech G29 and G920 are also a bit noisier than the more expensive belt-driven models.
