The beds at the S/D are only heavenly if your idea of a great bed is one that's relatively soft. DH and I found the Swan beds very uncomfortable, since we both prefer to sleep on a much harder mattress.
If mattress size is an issue, keep in mind that the value and moderate resorts all have full-size beds. You have to pay extra for a guaranteed king bed, and there are no queen beds at the values and mods. At the deluxes, though, you automatically get a queen bed and can pay extra to reserve a king. But, all mattresses aside, there are lots of other criteria you can use to choose your resort--as I'm sure you know already. For just a few examples: price (that's probably the first consideration); proximity to your favorite park(s); the theming that's most appealing to you; amenities; etc.
One of the problems with reading these boards is that you get such enthusiastic reports about everything, right alongside scathingly negative reports about the very same everythings. It can really be confusing.

Sometimes it's hard to tell if one is more in line with the positive or with the negative reports about any particular place.
Maybe, ignoring what anyone's saying about any particular place, it might help you to merely look at photographs of the rooms and grounds at each of the resorts and see what most tickles your fancy. There are loads of resort and resort-room photos at allearsnet.com. Check it out when you get a chance.
Choosing a Disney resort is the kind of thing that can drive a person mad...but it's a fun kind of mad!
