Would like to hear from Longhorn owners

I'm planning on replacing my 08 this fall and am looking at the luxury end of the current crop. I've seen the Denali and King Ranch but not a Longhorn yet; is it worth the extra $$$ over the Laramie?

How are the seats? Mine are crap and give near zero support after 2 hours.

Would you buy another one, or choose a different trim or truck?

Thanks.
