P-AWS and SH-AWD for snow

I know that there have been a couple of threads kind of addressing this issue, but as I look at the reviews of the 2.4L with P-AWS I am rethinking my first choice of TLX.

I am in CT and although we don't get a ton of snow, we get enough to make winter travel a pain. I have an 07 TL that I run all year with my Michelin all season tires. I hate driving in the snow b/c I slide everywhere. I know that snow tires would probably solve the problem, but as I look at my next car....probably in about 1 year, I would like to improve my traction in the winter. I was originally thinking TLX V6 with SH-AWD. The great reviews of the 2.4 P-AWS however have me leaning towards this model.....sounds like a blast to drive and I put on a ton of highway miles, so the better mileage is very appealing.

Do you think that P-AWS (with or without snow tires) would be more than enough for winter travel, so is SH-AWD a must? I realize that P-AWS is not specific to traction, but I assume that will improve some control in snow. I have never driven a P-AWS or SH - AWD Acura....all of mine (for past 25 years have been fwd with all season tires).

Any feedback would be appreciated. Thanks
