Pros: much simpler to manage a small number of things.  If you don't have
radically different retention policies or some regulating influence
suggesting separation, a single domain sending information to a single pool
hierarchy is perfectly fine.

Cons: none if the conditions above are met.

In some cases, I like the idea of two domains: one for non-critical systems
and one for critical.  For the critical systems, build your pool hierarchy
with a collocated tape pool for faster restores.
