It has better performance for many operations. I made a very detailed
performance comparison here (against Python 3.1):
Undoubtedly, you can find sequences of operations where Python's built-in
list type has better performance by a constant factor. Python's built-in
list type is more memory-efficient for small lists (blist's memory usage for
small lists could be improved to be similar, but I haven't gotten around to
making the necessary changes.)
