The short answer
The Hummer H2 offers power, while the Toyota FJ Cruiser excels at fuel economy instead. Choose the Hummer H2 if you prioritize power in daily driving, or the Toyota FJ Cruiser if fuel economy matters more for your needs. Both are covered by real owner reports on CarWizz.
Overall
Sentiment is deeply polarized, split between strong affection for the vehicle's character and significant frustration with its ownership costs and reliability. Long-term owners express a passionate, almost irrational love for the H2's imposing presence, comfortable ride, generously appointed interior, and its capability as an "absolute unit." This is consistently tempered by very frequent reports of exorbitant operating expenses, particularly fuel consumption in the range of 10 mpg or less, and recurrent, costly electrical and mechanical failures. The vehicle is widely recognized as a competent and uniquely capable off-roader with serious hardware, but the consensus is that it was predominantly used as a suburban status symbol.
Best version to buy
Insufficient owner data available to designate a specific model year or trim as "best." Discussions reference 2003-2007 models without clear preference. The unique SUT (pickup) variant is mentioned but not comparatively evaluated.

Overall
Extremely positive sentiment regarding long-term reliability, durability, and off-road capability. The vehicle is widely described as a "dream car" with a cult-like following, praised for its overbuilt nature, robust 4.0L V6 engine (1GR-FE), and exceptional resale value. Owner discussions consistently highlight its ability to reach very high mileage (200,000-300,000 miles) with proper maintenance.
Best version to buy
Trail Teams Special Edition: Specifically mentioned as a rapidly appreciating collectible with factory off-road enhancements like 16-inch TRD wheels for better sidewall, often commanding 2-3x original MSRP. For general use, models equipped with the automatic transmission are recommended over the manual due to noted issues with the 5-speed manual. 4x4 with a rear locker is the desired configuration for serious off-road use.
