Yes, you have more options with the transfer case, but 4hi is the same as awd.
Anyone drive their V6 4Runner in 4wd all of the time?
Awd = front and rear diff(usually open) and a limited slip center differential
4wd = front and rear diff(usually open like our t4r) and a limited slip center diff, an option to lock, and usually with a transfer case to add low.
Older school 4x4s did not have lsd center diffs which is why they should not be operated on dry pavement when engaged in 4wd.
I guess we think of 4x4 as more manly so companies still refer to it as that rather than saying you have an awd truck
To me “real” awd is lsds all the way around like my 02 WRX
