Kyle,
The only two people I know who played both in consecutive days, both of whose opinions I respect a great deal, rated BCG at a 9.5 and OS at about a 6.
Of course, that may be a minority opinion based on some polls. I had an invite to join them the next day but sadly had to get back home for work-related duties.
I suspect that better golfers don't like some of the quirk and chance at play at BCG and feel OS is a "fairer" test, but for those who appreciate courses where there are any number of great "match-play" holes, I can't imagine asking for much more fun than Boston.
