This actually reinforces the point that AWD helps you accelerate in a straight line, without regards to stopping or turning.

Right. Come DOWN that hill and stop or turn and see what happens...AWD doesn't help you.

can't get down the hill if you never make it up.....

In order for them to be able to handle high summer temps, the compounds get hard below about 40-45 degrees F. Hard compounds reduce grip, even on dry or wet pavement. Allseasons also have less aggressive tread patterns to compromise smooth quiet ride, fuel economy, tread wear. Winter tires have no such compromises.
but then how do A/T tires on SUVs & pickups do so well all year long? just asking....

A/T tires don't do so good on pavement. They are very rough riding and very noisy.

Shouldn't be all that rough of a ride on the tire's part, especially considering the tall profile and the relatively soft rubber-compound for off-road traction. Any roughness in the ride is more likely to be from the firm off-road springs and shocks. Noise, though? Yes, with a block-tread pattern like that, you're probably going to get at least some road noise.....just how much depends on how aggressive the pattern is.

Rough more as in vibrations rough.

An AT tire will have much better grip, but it will have the same drawbacks when it comes to rubber compounds and temps, and the tread patterns aren't specifically designed for snow.

If you don't do any off-roading regularly, you don't want to drive around on AT tires like that all year either. Loud, rough.

Went from all season to all terrain tires on the family Explorer. I can attest to much increased road noise and a slightly rougher ride. Tires are heavier than all seasons. After a year there is slightly more wear and the tread life of the tire is rated lower, but it is much better off road and in the snow. Trade offs, pick and choose what makes the best compromise for your use

Just a clarification, all terrains are also all seasons. You didn't go from all seasons to all terrains, you simply went from a street biased all season tire to an all terrain all season tire.
