What platform are you on? For the price of the G Pro, you could also find some other brands like Moza and Simagic for the same price. If on console, then it will be one of the strongest bases available, and it would be good to buy it over the RS50

If your only goal is the best force feedback with the least chance of disappointment, the Logitech G PRO (11 Nm) is usually the safer pick at the same price because the extra torque headroom helps it deliver strong, detailed FFB without “clipping” as easily in higher-load corners and heavier cars (you can also run it at lower strength for detail). The two concerns you mentioned are real but tend to be manageable: Logitech explicitly notes the base has active cooling and that, if it ever shuts down, you should leave it powered and let it cool before resuming (which strongly suggests thermal protection is built-in rather than “it just dies”).

That said, there are user reports of overheating/FFB dropouts after extended sessions in some titles/settings, so it’s not something I’d pretend never happens.

On the wheel angle, the “desk clamp angle feels too steep” complaint shows up from desk users, and the practical fix is usually a wheel stand/cockpit with tilt, or physically spacing/shimming the rear of the base rather than relying on the clamp alone.

The RS50 (8 Nm) is getting good early impressions for smooth, consistent FFB and TrueForce immersion, but it’s newer and you can already find scattered reports of quirks/bugs depending on platform/game, which is normal for fresh ecosystems.
So: pick the G PRO if you can mount it on a stand/rig (or you’re willing to solve the desk-angle ergonomics) and you want the highest ceiling for FFB; pick the RS50 if your priority is a more compact, “new-gen Logitech” package and you’re ok trading some ultimate FFB headroom for something that, in reviews so far, feels very polished for the money.
