My general preference is rather well-known, and I quote the advice I
gave in "Python in a Nutshell"...:
Some of the functions callable on specifically-typed objects [...]
duplicate functionality that is also available from PyObject_
functions; in these cases, you should almost invariably use the more
general PyObject_ function instead. I don’t cover such almost-
redundant functions in this book.
However, I don't go as far as suggesting PyObject_CallMethod and the
like... I'd much rather have abstract-layer PyObject_... functions,
as long as they're applicable to two or more concrete built-in types
(for example, IMHO adding PyObject_Clear is a no-brainer -- it's
obviously right). And I'm on the fence regarding the specific issue
So, having carefully staked out a position smack in the middle, I
cheerfully now expect to be fired upon from both sides!-)
