I'd say OEM (memo to self make sure none of the OakTable sees this - ooops) as an interface to ASH, with one *huge* caveat that of cost. ASH measures pretty much the right things whereas statspack and AWR (as generally delivered) don't. OEM makes it really really clear in nearly all cases where you should be looking. If you are a command and script person (as I am) then you really really have to compare and contrast fault finding using the OEM and ASH combo to your old scripts. Better yet get a newish dba or developer to walk through the same exercise.
