I would try to find a store where you can try them both as the decision is subjective. I recently bought a E-PL5 and it is very impressive with its larger display, ability to point to a subject on the display for focus point, high ISO capabilites, fast autofocus, and the new separate flash unit is a nice step up. The little flash has a tilt capability to bounce the light and not have the direct flash look as with an on-camera flash. The 14-42mm lens is a good one for street photography though it would be nice to be able to use a 50mm f1.4 lens on this camera to provide a 35mm equivalent 100mm f1.4 short telephoto lens. The 14-42 provides a picture angle of a 28-84mm lens on full frame which is pretty good and would work with your style.
