As they say, opinions are a dime a dozen, and most of them are based on perception, not science.
That said, the critical part of winter road traction is staying glued to the road regardless of snow and ice conditions. The most important traction enhancer is "driving for conditions", meaning to slow down as traction conditions deteriorate. A problem with many 4WD vehicles driving on winter roads is many drivers, overconfident by their vehicle's enhanced "starting traction", drive too fast, only to spin out on a slippery patch, or fail to stop when needed.
The critical part of winter traction on-road is the ability to stop. Dedicated winter tires help you stop sooner than later. One of the better "scientific" testing I've seen of tires for winter driving is HERE. Note that they put a tire from MT, AT, HT, winter studded, and winter studless tire classifications up against each other in a real world test. It's just one source and others should be sought out, but the results are surprising and informative.
If you want to maximize on-road winter traction there are tires that provide that. If you want greater winter traction off-road, then you would be advised to pick a different tire and drive carefully to the trailhead. Being that most 4Runners are driven mostly on roads, the answer for most in areas dominated by severe winter weather (like Alaska) is provided by research.
If you are set on an AT tire that does okay in year round conditions, the Cooper Discoverer AT/W might be your best bet. Cooper makes a LT/Load Range E tire in the stock 4Runner size (265/70R17).

Good luck!

The Contenders
We spent two days this past winter with Woody Rogers and T.J. Campbell, product information specialists for Tire Rack, comparing popular 275/65R18 tires on a twisting, curving half-mile section of track three behind the wheel of two identical 2016 Ford F-150 4x4s. The tire comparison contenders were:
Goodyear Wrangler Fortitude HT OWL SL (P-metric)
Bridgestone Blizzak DM-V2 SL (P-metric)
Goodyear Ultra Grip Ice WRT LT (E load range)
BFGoodrich All-Terrain T/A KO2 RWL LT (C load range)
Firestone Destination MT LT (E load range)
The two F-150 SuperCrew 4x4s came from the factory equipped with the Wrangler Fortitude HTs. The other four sets of tires were chosen by Rogers based on the most popular tread type with the highest customer satisfaction ratings from Tire Rack's customers: mud, all-terrain and dedicated winter tires — one studless (Blizzak DM-V2) and one studded (Ultra Grip Ice WRT.)
