Fanatec pedals are 80€ which are better than TGT stock one. If you want LC then its 120eur more. If you calculated for Fanatec LC then you also have to calculate Thrustmaster LC pedals that cost around 150€,so total Thrustmaster bundle would be around 900€.DD is 350 + new CSL LC is 200 + Rim is 200 + chip/thing for PS5 compatibility and Sony's licensing is 50 = 800 and it's far better than 750's simple plastic pedals with belt-driven base. 50 additional euros worth it...even 100.
So realistically speaking, Fanatec bundle is better and cheaper.
BUT if you only play GT sport, TGT is better. It really does have cool features and you can actually feel when car lose control or sliding
