No contest, Range Rover TDV8. Then get it chipped by a reputable specialist i.e. JR Engineering and it will out run a Supercharged RR and still return sensible mileage.
I'm on my second RRS and I love it. I only live about 15 miles from where they're made, so they're a pretty common sight locally. My first was an early RRS TDV6, which suffered from soem niggling faults, but my TDV8 has been totally reliable and after being chipped, is a genuinely quick car for a big 4x4.
The Tow Assist is fantastic and you can tow at pretty much any speed with total confidence. The interior is a lovely place to spend time, especially the new ones.
Get a Range Rover, you won't regret it.
