IMHO BOTH options are must haves
The 'comfort' seats are not as good as they were on the E53 models. But they are much better than the standard seats. For us, the ability to adjust the
shape of the seat back is worth the price of admission.
The rear climate package is a little pricey but worth it here in Texas for the factory tint and rear window shades, which are much better than the ones on the E53. The separate rear controls are very handy for groceries, pets and maybe even human guests
