If you simply want to compare dps, nothing else, but just pure dps between a shadow priest VS a feral druid (as what you mention just dps), Shadow priest should be higher.

What suggestion you want anyway? you question like half hanging like that.
In my guild most of the time, locks/rogues always top the dps charts.

I have a look at our WWS
one of our shy shadow priest (Tulang )manage to dish out 693 dps
