If you listen at moderately high volumes, the Pioneer SE-CX8 has insane hit because of the bass exciter. Lower volume doesn't engage the exciter. Wooduo 2 is very good for depth and good for hit. JVC HA-FXZ200 with the Wooduo 2 or NarMoo S1 ear tips have more depth and slightly less hit than Wooduo 2. JVC Xtreme Xplosives (FR202) have about as much depth and more hit than those two but have a less pleasing sound signature (and should for $25). NarMoo S1 loses a little hit but sounds a little better at a similar price point. I still haven't heard any Sony IEMs.
