they are all great resorts. i think you should look online at pics and pick the one that you think has the best feel for you. none is probably overall any better than the others, it's just subjective as to what each person prefers. you did mention restaurants. the GF has the most nice restaurants on property so you might like that; however, if you stayed at one of the other resorts it is a quick trip over there (for example, monorail from poly to GF is literally something like a minute and a half). GF is more upscale overall. You also mentioned scenery- what kind of scenery do you like? I would say the Contemporary probably is less scenic than the others, but I guess it depends on what you like to look at.
Good luck with your choice, you definitely can't go wrong.
