Yes, There's a definite difference between my 105K and 237K Elite's as you'd expect, but I still maintain that the Elite seats are some of the best long distance seats ive spent time sat in on any car. I think the range of adjustment is equally as important as the sculpture and support of the seat.
I'm not a fan of lots of adjustments, as it encourages designers to skimp on the basic design/installation. And then you end up constantly fiddling with the adjustments to stay comfortable if you ever managed it in the first place. Mum's '12 Focus is like that;it has the usual rake, front back, height, lumbar etc, but the adjustments are far too coarse and the height adjustment is done by a weird mech that moves in more than arc. With 3 of us driving it, I can never get the seat in the same barely good enough position twice. The Omega seats got all of those right(they're by Recaro, so that's hardly a surprise) so that I took a few seconds to adjust the seat when I bought the car and never fiddled with it again. The memory function was useful to return to that on the few occasions my sister drove the car.
I found the sports Recaros that Ford used in the '70s and 80's to be better still: perfectly supportive and instantly comfortable, even though they have barely any padding on sheet steel frames and only the rake was adjustable. Somebody spent a lot of time actually designing the things to suit real bodies!
