There are no great views at BCV
I personally happen to prefer the quiet pool because it offers the most activity if your into people watching, I've had pretty much all of them except for the courtyard view which would be my least favorite. I also always avoid the 1st floor and try to get as close as possible to one of the two elevator locations. If you will have a car being near the parking lot is a plus if not request something closer to the main BC resort, which would be closer to the bus stop and a little shorter walk to EPCOT. A woods view might get you some views of EPCOT fireworks, the upper floors would be best.
