Some additional thoughts. The AWD system on gas vehicles typically offer up to 50% power to rear wheels. The hybrid is more limited, as the only power to the rear wheels is that which the rear electric motor provides which is typically about 20 - 30% max of total power. Consider any Toyota hybrid AWD system to be an "assisted FWD" setup. Most of the drive comes from the front wheels with "some help" from the back. I have a Lexus RX450H AWD which shares Highlander Hybrid specs (earlier gen though, but systemically still similar) and its merely "ok" in snow (better than FWD). But I also have a Subaru and its AWD system is significantly better. It has a "real AWD". Someone mentioned Toyota's new torque vectoring AWD as an option on gas models. Unlike Subaru and Toyota's more conventional gas AWD systems that use the brakes to limit wheel spin on one side of the car to redistribute power when needed, indeed this new system uses electronic clutches to direct power away from slipping wheels without having to rely on the brakes. Sounds better in theory. It also uses "drive line disconnect" to completely remove the drive shaft and rear differential from spinning when just cruising for better fuel efficiency. Nice, but extra complexity. I think the Subaru will always have a hint of an advantage because the rear wheels are always prepared to be driven, whereas in all of Toyota's AWD systems, the rear wheels really need a moment to wake up when the front wheels start to slip (perhaps the different traction modes might help this, on my hybrid Lexus snow mode seems to put a pinch of extra power to the rear, while removing a pinch of power from the front). I think the difference in most instances for most people would be negligible, but if you are indeed wanting the best immediate response, Subaru. On mine, with good snows, I punch it on a green light in 3 inch of snow, it just goes. No "maybe"s, no "let's consider our options", it just goes. My Lexus hybrid AWD with good snows, I punch it under same conditions. It still goes, but with some thinking. Hmm, front wheels slipping, lets ease of the engine power, give a chance for the weaker rear motor to push a bit, oh, fronts have some additional traction, lets give some more power up there. It does fine, but its no Subaru. I have a RAV4 with torque vectoring on order, I'm really interested to see how it compares.
