2010 Suburban AWD or 4WD, Confusion ?

is one any better in the snow than another?

I avoid the snow at all costs but do you need 4lo for snow? I alway pictured that being for low speed rock crawling. high traction low speed grunt. snow being mostly a lack of traction aren't you mostly relying on the stability control/abs to find traction?

I have been in some really deep snow and have never needed 4LO.

The need for 4lo is extremely rare, like if you were stuck already, otherwise it serves almost no use.
Unless your intention is to purposely go to some sketchy places often then your going to want to have additional means of extraction anyways. For normal driving it's unlikely that you would ever need it

4Lo is basically just more torque multiplication advantage due to super low gearing. So basically if you get stuck as mentioned and wheels aren't spinning somehow.

I think top speed is like 20 MPH at engine redline or something like that. So yeah, usually not needed unless you have to.
