I didn't vote because I don't think one is better than the other...just different.
BTW, there are two club level buildings at the GF...the main building and Sugar Loaf. Royal Palm Club in the main building is more expensive.
Anyway, we've stayed in RPC once, SL 3 times, GV Hawaii 3 times I think and LV Hawaii 4 or 5 times. Lagoon view in Hawaii is an absolutely stunning view. The lounge also enjoys that view. Neither lounge at the GF has that view. No view at all in SL and just the grounds in RPC although listening to the music drift up from the lobby is very pleasant indeed.
At the GF some RPC rooms look toward the marina with the castle beyond,,,the view Garada enjoyed. But other rooms look toward the courtyard which is what we had. It's pretty but I prefer the garden view rooms in Hawaii to that with the exception of the room Garada had there.

In Sugar Loaf, the view is either of the courtyard or the marina. We've had marina each time and I do love that view but it's nothing like the view from lagoon view rooms in Hawaii.
I like both rooms although we haven't been in the newly redecorated rooms at the GF...they do look pretty. I actually prefer having the sink in the bathroom which is the setup at the Polynesian....more sanitary. I like the towel hampers at the GF.
Breakfast at both is continental and very similar. I
much prefer the evening appetizers at the Polynesian but the afternoon tea at the GF has really wonderful scones. I like that the GF offers champagne.
We've had great interaction with CMs at both.
Both are wonderful experiences. I really don't think you can go wrong.
