I bought an AWD a couple of years ago. I had a couple of hills on the
way to work and passed cars sliding all over. When you put it into snow
mode you get 50-50. The traction control though will vary it as needed
from 90-10 to 10-90. In Eco or regular mode it is 40-60.

I've since retired and have no plans to drive on a snowy day again.
Nothing that can't wait for the roads to be cleared.

If you live in snow country, then these traction schemes make sense.
If you don't live in snow country, chains are a lot cheaper in every way.
And better.

They're just not as convenient.
I'll NEVER drive with chains on a front wheel drive vehicle. I've had
enough chains break on RWD vehicles - and they do a lot of damage.
They are OK for getting out of a tough spot, but you HAVE to remove
them before hitting the highway.; Since I've goneback to dedicated
snows, I've not had a situation where having chains would have been
any advantager (and I'm in "snow country")
