Help me choose between the LX450 and the GX470 - which one is right for me?

I'm torn between the LX450 and the GX470, both of which I've always been drawn to. The LX450's rugged off-road capability and V8 power are enticing, but it's getting up there in age and maintenance costs might be a concern. On the other hand, the GX470 offers better on-road manners and a more modern design, but its capabilities in rough terrain aren't as well-established.
