Be careful you're not comparing apples with oranges here,
though. Pyrex is capable of generating quite efficient code
for many things, it's just not as automatic as Cython.

For example, I gather that Cython will generate a test
for a list object and index it using list-specific calls
in that case.

Recent versions of Pyrex will also use list-specific calls,
but only if you declare it as a list. Theoretically this
should be even faster, because there is no run-time test
involved.
