IMO... the A8L is a better tub, so is the A8. The A8D is awkward. The lounges are different sizes.
Plus, you should pay less if you go with the A8D, as it costs the dealers less. And you get one less jetpak.
My suggestion, if you are going off a picture, stick with the A8.
If you can at least sit in them dry, then consider the A8L or D. My wife and I switched back from a HSS Envoy to a Grandee not long ago. We missed having the cool down bench versus the lounge, especially since my wife just floats out of the lounge.
