As always, it depends on your application and budget.  If you have a
lot of computers, for example, small batteries in each computer that
are long enough to deal with a mains switchover (i.e., up to a few
minutes) may be preferable because you want to save space in the rack
(and you want to avoid the relatively low efficiency of whole-room
UPSes).  Since your batteries tend to last about as long as you would
keep the computers (if compute is your business), there's one less
maintenance schedule to worry about.
