CB pool has a slide. </list of things that are better at CB>
We moved from CB to AoA (POP's sister resort on the other side of the lake) on our last trip and LOVED it! We were worried about the buses @ the "value" resort - they were great! The food court also exceeded expectations, and we found the front desk staff to be really helpful. POP and AoA are +Value resorts, nearly Moderates.
Meanwhile, over at CB...
The place is VERY spread out and you will need to take a bus, or a lengthy walk to do anything. The internal buses takes as long as the resort buses. There are smaller quick service food places scattered throughout but we found those to be seriously lacking - NOT Disney quality and very little selection. Some will say the layout of CB adds to the laid-back atmosphere - yeah, OK, whatever.
The Skyliner will get you to CB from POP if you really want to see it, but stay at POP, even if it costs more.
