I'd miss the GLOBAL express down, where all four windows (or five on the SUT) go down and up at the push of one button.

Sorry for the bold! Just trying to highlight the quote.
You say you bought the H2 for offroad and reliability, yet you seem to put priority on interior space and towing. Do you need them?

I did buy it for the off-road ability, and reliability, which both vehicles share, so the question really comes down to other factors.

As for towing, that is important to me. Interior wise, I like having the extra room for big items and the shoulder/hip room. Do I need them? Well, I appreciate them at any rate.

Really, I like the Stabillitrac especially, since it has been shown to reduce single vehicle accidents by 40-60% (NHTSA.GOV). And head side impact protection reduces fatalities by 30-40% in side impact accidents (IIHS.ORG).

Also, my current insurance on the H2 is about $1600/year. It would only drop to about $1300/year on the H3. Slight benefit there.

As for the particulars like approach/breakover/departure, I'm not sure 1 degree of difference from the H2 or H1 makes much difference to me (H1 ALPHA is only 1 degree more in departure!). Granted, I will have the off-road suspension package with the 33" tires.
