I use rpm for basic stuff because it runs faster.  For example:

$ time yum list installed
...
real    0m17.069s
user    0m0.857s
sys     0m0.675s

$ time rpm -qa
...
real    0m4.714s
user    0m4.457s
sys     0m0.120s

Yum tends to take a while to read in its databases before it processes
your command.  So for simple commands, it is faster to use rpm.  On slow
boxes, it can be significantly faster.
