Two things, bigger motor does NOT mean worse mileage. Our Denali gets almost the same mileage as our H3. The engine has to work less hard. With the H3, any hill, any towing, and you're testing the pedal to floor minimal clearance quite frequently. With the Denali, you NEVER squash the carpet unless you mean it! We had a 5.3 Yukon before our 6.0 Denali. The 6.0 performs much better and gets even better mileage than the 5.3.
The H3 is heavy beyond it's size, and it needs a larger motor accordingly for people that are used to having performance on the road because face it, the H3 is used on the road.
The H3 most certainly has a power problem, unless you're not used to anything else. It's more than adequate, particularly offroad because of the 4.56 gears and the 4:1 tcase.
IF they ever put the V8 in there, they'll most certainly need to upgrade the axles. Mine's in the shop for the second time for the rear end. (no biggy, they're covering it, I'm ok) I'd LOVE to see a 6.0 with a portal driven front axle with locker, and a Corporate 14 bolt with e-locker. THEN, you'd have what I'd consider worthy of the Alpha badge.
