The F! FP viewing areas are set up with three different colored FPs: Blue, Green, and Yellow. There spots within each viewing that offer an excellent view and spots that offer an obstructed view. In terms of "better" it's not entirely clear cut. Some folks really like Green because it includes the PotC bridge, but there are only a very few FPs each show in that color area. Yellow is probably next "best" color and then Blue, but that does not mean the worse viewing spots in Yellow are better than the best viewing spots in Blue.
F! has one distinct advantage over WoC. Much of the show is slightly elevated, so you don't have to see the water to see half of the show like you do with WoC. So even further back in the viewing areas you'll still be able to see a lot of the show (that does not mean that you'll see the full show because some things are low(ish) to the water, e.g., the princesses on the rafts). I dislike the viewing areas for WoC because I have trouble seeing over the people in front of me, so I feel like I only see half of the show (the mist screen projections and the water when it's shot into the sky). So, F! is "better" in that way, but like anything, you won't get the full effect of the show if you can't see over the people in front of you.
