For me, it would probably come down to at which park I intended to spend more time. If you love Epcot, BCV sounds great to me! Only caveat I've heard is that the buses aren't ideal for MK heavy trips. If you love MK, then it would be very nice being able to walk there from BLT!
I've never stayed at BCV, since Epcot is my least favorite park, and I usually go once per trip for dinner and am done. But the theme there is for sure more appealing to me than the atmosphere at BLT. However, I think you will have a much more difficult time finding what you want at BCV vs. BLT in early November, because of the F&W festival.
I think it's really just personal preference/taste and convenience to your favorite things to do!
Good luck with your decision!
