The L96 is a beast when it comes to reliability, especially for a daily driver like your Denali. You’re right — you’ll lose a little horsepower on paper, but you’ll gain a ton of durability. Biggest thing will be getting a proper tune to deal with the different compression and no VVT if your L96 doesn't have it. I actually spotted a l96 engine for sale near me recently, and they’re pretty reasonably priced too compared to rebuilding an L94.

If you had a few L96 ready to pop into a 07-14 Denali for sale with a blown motor you could make a nice profit flipping them.

An 07/08 Denali running on reg gas with an e85 motor is a huge plus. A 10-14 Denali with no AFM, running on regular fuel and the longevity of the L96 pretty much makes for the perfect luxury tow vehicle.
