Wish I could agree, but I can't. While not 4runner specific, I have direct experience with running 2 sets of rims/tires and just a single "does it all" tire over a decade in Wyoming, Montana and Colorado... with the "one tire for all" finishing out life with a move to Georgia were I've been back to rain focused all-seasons.
At the bleeding limit, a dedicated snow/winter tire Might be technically better, but I couldn't tell with my trips to the ski slopes and my wife couldn't tell doing her ~1000 mile commute weeks. Studs were absolutely worse as a daily driver, only being good/great in a tiny range of conditions. The winter rated all seasons we ran were the Nokian WR line (3 different generations), and they were good enough to get me off the 2-set merry-go-round. I was astonished at how well they handled the heat of Georgia too (got the full rated life, with ~25k miles being in GA), were phenomenal in heavy rains/flooded roads where I expected hydroplaning.
And that's for tires from 9 years ago, I can only imagine how much better that "winter rated, all season" segment has gotten.
Since we all only know the best we've tried, opinions can be vastly different. But please, don't poopoo a product you have no experience with. There look to be several offerings out there in this "Winter rated, all season" category, and they are absolutely what I'll be running when I manage to extract myself from Georgia and get back to a real winter state.
