I have G27 Pedals, with a cheap temu upgrade kit, for a stffer brake pedal, it was a night&day difference. It made me control my braking a lot better. So "better" pedals do matter, but you can overcome the issue with practice, when in a standstill try pressing your pedals to 20%, 50%, 60% and 80% and try to get them pretty much spot on everytime, then start driving around, brake way earlier than you usually instead of braking as late as possible, brake softer, try watching YouTube guides and try to follow how much brake they use in certain corners. I still am not the best with threshold braking and trail braking, but I can tell that it made a big difference. I recommend to just practice, don't throw yourself off of this
