PT4WD in snow/icy roads

Hi guys, I’m thinking of getting my first 4Runner and I’m interested in the SR5 6th gen, I’m wondering how the PT4WD handles in Icy slippery conditions, we don’t get a lot of snow here but sometimes we can have some Icy/ slippery roads. I thought about different trims with FT4WD but the price difference is crazy, also was looking at the TRD off road but it’s PT4WD same as SR5 and not sure that it will handle any better in snow.
