If the pool is overly important to you, BCV is a good choice. But honestly, we kind of like Boardwalk better. We've stayed at both and the Boardwalk just tends to be more enjoyable. They have updated a lot of the rooms twice since we've owned there. Really, both are great for getting to HS and Epcot. We usually walk to Epcot and end up taking the boat coming back.
Keep in mind, the further you are from the main desk at the Boardwalk, the closer you are to HS. We've actually walked to HS a few times and even caught the boat at the Swan and Dolphin instead of the main Boardwalk dock. Both resorts are great and are in the mid range of points per stay. Boardwalk tends to offer a little better options on views, if that's important to you.
My wife is a HUGE Boardwalk fan. She really hates staying anywhere else. I'm more of a BLT fan, but I like the Boardwalk.
