We're getting closer to having experienced all of them! The only ones I can't judge are AKL and YC.
The best food and services goes to GF RPC. It was a notch above all other. Fresh sheets were kept in cute baskets outside each room every day (no rolling housekeeping carts hanging around everywhere...), the shampoo was the green lush kind that I'm now hooked on, they would engrave GF on the TP and tissue each day....I know those are just little things but they all add up. Food was outstanding!
The best location and views goes to Poly CL. Specifically a LV or TPV room. To us, there's nothing like sitting on our patio/balcony and seeing GF, the Castle, and CR....and swimming in the main pool while watching Wishes too. The Poly lounge has the best view in WDW, just our opinion of course, but the entire wall is a window with the most amazing views! A part that we really love and need in a CL is to have easy access in and out. We don't want to hike back and forth everywhere, and Poly offers easy access to the lounge, both pools, the main building & monorail, and also the boat launch.
