BB6-7, 9-10.

But I wasn't too big a fan of the BB9 and 10 exterior (especially BB10's) compared to BB6's and 7 as the crowds were significantly smaller, the oval stage with the eye design was ugly and I much preferred the circular stages which lit up purple/yellow that were featured in BB6/7. They also got rid of the TV screen on the facade of the house and it just looked ugly and blank.

I also liked BB5's exterior. BB8's was okay, but that long walkway was just awkward in retrospect.
