"Worth" is as subjective as any conversation can get.
I love the GF. It's a beautiful hotel with great amenities. The atmosphere is very fancy. I love Pop Century too. Different reasons for each.
I have the good fortune that the cost isn't a critical factor. I can afford to stay where I choose. After many trips, I've managed to stay at all but dedicated DVC resorts and Coronado Springs, I've enjoyed all of the resorts. I now tend to stay at one of three hotels: Beach Club, POFQ or Pop Century. GF is nice, but the limited number of rooms with decent views is the biggest drawback. Beach Club gets the nod when I'm going deluxe because it's stumbling-distance from EPCOT. Most trips I stay at POFQ because it's "quaint" and beignets. If I'm going solo I'll often stay at Pop.
If I were saving up for a special trip, I'd probably edge toward a Moderate resort, amenities are better, but not fancy. The beds are better, but not luxurious. Having more available for souvenirs and treats, maybe a guided tour would be a better use of limited resources. At least IMO.
