Always good if you ask me.
Too much hurts handling, fights the steering. Too little and tires slip. Try driving a 4wd rig with front and rear locked diffs, can’t turn for shit and it eats tires. Now try a 4wd with open front and limited slip rear like an auburn pro unit. Good on road, good in wet, fantastic in off road, spins front slightly on extreme terrain. Mostly that’s the best compromise. Traction can be best achieved with proper suspension keeping tires applying equal pressure.
Everything is a compromise, just have to make the best compromise for the majority of encountered situations.
Well you sound like you have a lot of experience and are very practical about vehicles.
