Insertion sort performs better by all the simple measures: it's better
on array reads, on array writes and on compares.  It's better (or no
worse) than bubble sort in every case I've tested, and that includes
exhaustive testing of all permutations of small data sets.  These are
simple measures for sure; that's why I asked why you if you had data to
back up your advocacy for bubble sort -- it was possible you had better
data than I do.

So why are repeating this old canard?  Bad ideas won't die if everyone
just keeps repeating them.  On the other hand, I'd be very happy to find
a data set that makes bubble sort look like a good choice (I like to
learn new things), I just haven't ever found one.
