Well that’s just mean…
But to answer your question in terms of traction, an AWD with a center diff lock should act more or less like a part-time 4x4 in 4hi. But the traction isn’t the whole picture-- if the ground clearance isn’t very good or if your tires aren’t in the best shape you can have problems. The low range can also be very handy, although perhaps less of an issue in an automatic.
Also, I’m not sure what effect airing down the tires would have on a modern car with tire pressure monitoring, ABS, traction control, stability control, etc.
