It depends. Leave it on for normal safe driving. If you get stuck in deep snow and need to "rock" the car out -- allowing the wheels to slip -- then turn it off. Press for three seconds to disable. Press again to enable.

"Better" is a relative term - "better" than what?
DSC controls "better" than DTC, but
DTC drifts "better" than DSC... which can be fun under the right conditions.

I routinely use DTC instead of DSC on slippery roads where I need to merge into moving traffic from a standing start (like from a side street into a busy street). With DSC, I will accelerate, but any slippage and I might come to a nearly complete jerking stop until it figures everything out. With DTC, I can safely "drift" it into traffic (I use the term rather generously) without the dangerous hesitation a slip-correction can cause.

At all other times I drive with DSC ON as it is the safest option to correct unexpected screwups.

You can also turn the system off completely if you have the space to safely enjoy being a complete goof in your car.

I would recommend you find a large empty snow-covered parking lot with no obstacles and try it out for yourself doing aggressive figure-8's to see what the 3 settings feel like. Good clean fun.

Maybe just me but I nearly always use DTC on snow/ice. It allows a little bit of wheel spin & drifting and does not cut throttle. Where I live you'd almost always be cutting power with full DSC which is annoying. The only time I'll run with full DSC in winter conditions is when I want to use cruise control.

+1. I pretty much do put DTC on everytime I drive the car otherwise I can't floor it in 1st if need be. If it's snowing and I find an empty lot or i'm trying to do a 0-60 pull then i do full traction control off
