Several of these are "features" exist to fix broken parts of Oracle (like query/planner hints, planner adjustment, etc). Officially (per Oracle) the planner should be good enough so you never need to use a hint, but realistically all of these are "features" because the built-in systems aren't good. So, granted, other databases don't have Oracle's hacks to fix their broken stuff but I'm not sure why that is an argument FOR using Oracle rather than AGAINST. Hints are fragile hacks.
