UEL will gain more top end power but lose torque. Very gay.

EL will gain more top end without sapping the torque. Very win. Sound like a Honda though.

As per everyone else, go speak to your tuner and ask their opinion. They will know the current limiting factors. From what I remember, Sean used to get 300hp/450Nm out of the 06 STi's when they came out. So tell him not to be weak and dial in the car properly.
