The Swan is lovely, IMHO. It has less of a convention resort feeling than Dolphin, IMHO and the rooms and beds are very comfortable. Swan/Dolphin also has a lovely pool area and some of the best restaurants on-property, IMHO. That being said, YC and BWI feel more "special" to me, so it really depends on how much more you are willing to spend for a more themed experience. If saving money is your top criteria, I would choose Swan in a heartbeat. If you want a more Disney-feel, I would go YC over BWI. I love the Boardwalk area but we have had some very loud rooms at BWI and you have to go outside to access any type of QS or TS restaurants. YC is nicely themed and is very low-key. I would also suggest looking into a studio at Beach Club Villas, if available. We love the villa building at BC - very quiet, a lovely quiet pool next to the building and super quick walking to EP, the Skyliner, the BC QS and the park buses.
