As well as the DFGT in my racing cab, I've also had Logitech stuff in the past (a G25 and then G27) too. I've always found them to be well constructed and good value. I've never owned anything from Thrustmaster as I always percieved them as cheap-looking. I never liked that massive wheel and pedal set they produced either (was that the T300? I'm not sure..)
That said, Thrustmaster now make a very high-end PC/PS4 wheel (a snip at £700!) but I don't know if it's any good or not. For 700 quid though, it better be!
Short answer: Logitech.
