Complexity depending on your perspective.  The implementation might be
more complicated to code, but by and large the major implementations
after years of experience seem to be very stable now.  If the physical
topology and stability is increasingly "interesting", RIP may be a more
complex protocol to use and troubleshoot than OSPF.  In essence,
dealing with loops and topology changes in RIP involves a set of
incomplete and unsatisfactory hacks for more than the simplest of
environments.

As an implementation of distance vector, its at least useful as a teaching
tool about routing theory, history and implementations.
