Guaranteed you would have had a worse boarding position had you checked in 24 hours prior. When you purchase EBCI does matter and affects your place in the queue. Buying your tickets and EBCI as early as possible will result in a better boarding position, perhaps you purchased relatively late? A low B boarding position is hardly a "bad experience" and you must be living right if this is the worst thing that has ever happened while flying.
The benefit for me of EBCI is not having to worry about it. I can get my boarding position anytime within 24 hours of my flight and my boarding position is the same regardless. I can even just show up at the airport and get the boarding pass there.
