If we want to talk semantics here, technically SUV's don't exist anymore. There are only a handful of true body-on-frame SUV's left in the world, and the rest are crossovers because they're built on car, or modified car platforms. Alas, people will still call them SUV's.
You only showed pictures of crossovers. Anyway, I also driven the Nissan Juke (a cousin bought one) and it felt really cheap as well. Ride was also horrible. It looks horrible on the outside, in my opinion. I can't give much inputs on cars in general because I have limited experiences with it. The GL450 is my first and only car so far.
I mean no disrespect Topre, but I think you were in the wrong frame of mind when driving the Juke. If the GL450 is your first and only car then you're going to have to adopt a completely different mindset if you drive any car that's worth 2-3x less like the Juke is.
That being said, there is a reason that you probably felt as though the Juke's ride quality was poor, and that's because from everything I've read, the Juke is set up to have really good driving dynamics, which at the Juke's price-point, usually comes at the sacrifice of ride-quality. I also would imagine many cars are going to feel cheap compared to the GL450, so sorry if I'm taking that criticism with a grain of salt.
Trent, in my opinion, if you can get past the styling of the Juke (I'm in the "it's so ugly, it's cool" boat) then I would totally recommend getting one! If you can afford it, get the turbo as well, because they're fairly quick, and you probably won't sacrifice much on gas mileage. The Hyundai Tucson is also a great pick, and another crossover where I would suggest getting the turbo motor! But above all, driving it is worth more then any advice I can give you, so go out there and drive it!
