I say HCH2 for better MPG, but knowing I'd be tempted by the sweetness of the TCH, I chose to not even look at it! The only reasons I kept away from this temptation:
(1) better MPG of the HCH2, and
(2) somewhat lower price of the HCH2, and
(3) I found nothing lacking in the HCH2 (although leather & bluetooth would be nice).

I can add leather and bluetooth if I desire (to spend the money ), and I'll still get the better MPG. Good enough for me. I'm happy in my HCH2.
