BF is just business class, the name is just a marketing tool IMO. but regardless, i will give credit to CO because unlike many of the business class cabins of several airlines, you can at least take comfort in knowing that you will never have a middle seat when flying business on CO, no matter what aircraft you're on. for solo travelers, who would enjoy flying biz if you're sandwiched between 2 strangers for 10 hours?

fortunately most airlines that have or are revamping their biz product are using layouts that eliminate the middle seat altogether...that VS suite setup/cabin design seems to be catching on, as evidenced by NZ, AC, and if i'm not mistaken isn't that the sort of layout DL is planning on using when they update their biz-elite cabins on their long-haul widebodies?
