What's more comfortable about SUV or a truck than a minivan or combi?
How is a tall hood increasing your family comfort? It only increases your ego.
Plenty of minivans also have tall hoods. I assume by combi you're talking about a station wagon, and in that case you're trading cargo capacity and the ability to tow boats / trailers / campers / etc... Ego has nothing to do with it - utility does. You can fit more people and things in a larger vehicle, this isn't rocket science.
I spent significant time recently in both a new F150 and a Toyota Sienna, and it isn't even close in the comfort between them. F150 wins by a mile by the sheer amount of space you have in that thing for both passengers and cargo. Not to mention the ability to tow.
