The Specs: On Paper

The Moza R21 Wheel Base and Thrustmaster T300 RS GT are both direct drive wheels with impressive torque ratings. The Moza R21 boasts a whopping 21Nm, while the Thrustmaster T300 RS GT comes in at 3.9Nm. Both have standard quick releases, but only the Moza R21 is compatible with PC. It's worth noting that the Thrustmaster T300 RS GT has a wider compatibility range, including PS5, making it more versatile.

The Ugly Truth (Real User Experience)

I've seen users struggling with notchy behavior on both wheels, but the Moza R21 seems to be particularly prone to this issue. Some owners have reported that their wheel feels notched even when a steering wheel is attached. The Thrustmaster T300 RS GT has its own set of problems, including overheating issues and reliability complaints. Users are reporting that the base can freeze mid-game or turn by itself full lock on one side. I've also heard about owners dealing with broken quick releases and having to replace the PCB. The big problem here is that these issues seem to be widespread, affecting a significant number of users.

Dealing with these problems is a nightmare. You'll spend hours troubleshooting, only to realize that the issue is with the hardware itself. And don't even get me started on the hassle of trying to contact customer support or getting parts replaced. It's a bureaucratic nightmare that will drive you mad. I've seen users who have had to send their wheel back multiple times, only to receive a refurbished unit that still doesn't work right.

The Verdict

Despite the issues with both wheels, I would recommend the Thrustmaster T300 RS GT over the Moza R21. While it's not perfect, it seems to be more reliable and has fewer reports of major problems. If you're on a budget and don't mind dealing with some minor issues, the Thrustmaster T300 RS GT is still a good value for money. However, if you're willing to spend a premium price point and want a direct drive wheel that's relatively hassle-free, I'd suggest looking elsewhere.

For users who are new to sim racing or on a tight budget, I would recommend avoiding both wheels altogether. The issues with these products are too widespread, and it's better to start with something more affordable and reliable. If you're serious about sim racing, it's worth investing in a high-quality wheel that won't give you headaches down the line.
