I think they ALL have value but for me, it's Sapphire, Aventura, Hard Rock & Portofino.
Sapphire is the best value to money if you're not going to the park in the day. Very easy to hang out in the pool and get drinks at Sapphire, then boom water taxi over to CityWalk. Even though you're not *supposed* to, I do like that Aventura has that level of access as well.
Portofino is just nice. It's great and I think that it is more quiet during HHN and I honestly appreciate that. The vibes and location at Hard Rock are UNMATCHED though. Plus that breakfast buffet is the best in the game. But back to my point about Sapphire, there's is a very comfortable and deserving 2nd place.
I guess if the chips fell I'd book Sapphire pretty fast.
