I think that depends on the snow, Zach. From what I've been reading, snow is a lot like mud in the sense that there are different kids. For some snow there's no substitute for flotation, while other conditions require digging to terra-firma.
The requirements of a tire for sand vs. snow can be very different, again depending on the depth and quality of snow.
For all that you've going to need a pretty broad compromise or run different sets of tires.
Some of the snow I've wheeled at Wharton would have been better with narrower tires, but even in that season, you can still break ice and end up in deep mud which wants a wider floatation tire because Wharton mud is "bottomless" -- that is, it's a result of an underground aquifer which makes the water go deep, deep, deep.
That's one of the things that skews tire discussions sometimes: we talk about "pure" wheeling environments when in reality many of us do such a mix there really is no single "best" tire I think.
Being the leaf spring bigot I've been accused rightly of being, lol -- I would suggest taking your time and doing front coils. Better ride when you do street it and long term I think you'd be happier. Many will disagree. What you will find is guys with leafs will defend them, and guys with coils will defend them. I've got coils in the front of my SAS in case you hadn't guessed, lol...
But coils are generally acknowledged as being a better choice up front for a DD offroad truck like mine. High arch front leaf springs are usually much harsher, but perhaps it doesn't matter to you -- it seems not to for some. I'm old though and like my comfort, lol!
