I somehow wound up obtaining both; I've got a righty DW 5002, and a lefty Pearl Eliminator. Both are really top pedals, but I like the eliminators because you can pretty much alter any setting on the pedal with a couple of twists of a tuning key.
I suggest, however, that you actually try the pedals out for yourself before you make the final choice.
OK for starters the PEARL PEDAL is a AWSOME PEDAL but expensive I just picket up a new AXIS-X wich PEARL copied the geometry from, the DW pedal is a different animal compared to the PEARL or AXIS geometry good luck
but if you're on a tight budget, then i suggest you try all double pedals you can get you hands on and feel which suits you better. i believe pedals are personal as your deodorant and buying them solely on the basis because people say this pedal rocks, this one is hot, etc. is not a good way to go. give all the pedals a shot and try each one of them and see which one suits you better. ^___^
