I think its the other way around, no?  inotify can give you events for a 
whole tree of namespace, whereas dnotify requires that you actually have 
all the directories open, which doesn't scale at all well.  dnotify is 
very definitely deprecated these days.

(Not that inotify is particularly easy to use...)
