If so, do you recommend it? why?
I'm trying to get an suv before winter starts but i'm unsure of what to get. Any feedback will be greatly appreciated.
TIA

Slightly different treads in a tire are going to make a difference if you're talking about increasing traction for a specific car (i.e., you already have a car, you're looking to increase traction), but if you have the choice OF the vehicle, then I'd go for more mass if you're looking for more traction.
Honestly, at this point it would be speculation unless we have hard numbers in front of us. But out of these two scenarios, you know which one I'd pick.
A) 4497 lbs. w/ winter tires
B) 6411 lbs. w/all year tires
Spoiler for which weight belongs to which SUV.

Page 13.
Highway tires on snow - traction coeffecient = 0.024
Snow tires on snow - traction coeffecient = 0.055
A heavy (6411lb) vs. light (4497lb) SUV (as you mentioned)
From the formula above, usable traction = traction coeffecient * weight.
Heavy car with regular tires = 153 units
Light car with snow tires = 247 units
The lighter car with snow tires has higher traction by about 1.5x times. If you put "studded snow tires" (instead of regular snow tires that I was talking about), that number goes up by even more.
For some reason on this site, the "ice" coeffecients are identical. No clue.
I found another useful sight during my research, http://www.unb.ca/transpo/mynet/mtu13.htm . It doesn't answer "this" questions, but it has a lot of the physics equations and formulas for cars (including traction coefficients on various pavements).
Traction coefficient for concrete is 0.7
Traction coefficient for snow/ice is 0.06 - 0.12
And if the ice coefficients are really the same for different tires (from the first site), then you were right that weight would be more important than tires. I dunno. Too lazy to continue researching it. It's not that important.
I'm a geek and proud

Dealer junk had me spinning the tires in the rain, got a set of All Weather Cooper S tires and set of Michelin Latitude X-Ice winter tires for the wintertime snow here in NY (as im a commuter so i gotta do the drive in the snow/slush to NYC)
I haven't figured that out either (though studded snow tires do matter if it's ice or snow), there may be something written in the report explaining it, but it's 80 pages and I'm not THAT bored, and ...
What does it do that a car doesn't?
My Ford Escort did just fine in last years record breaking snow.
