Help between Lightroom 4 and Oloeno PhotoEngine

Neither of those is a good option for processing X-E1 raw files. You did not specify how you intend to use the software or what kind of photography you do.

You should download trial versions of the applications you are interested in; then you can judge for yourself. You should also try Photoshop Elements. It is around $80, includes Adobe Camera Raw for raw conversions and has many of the same tools as Photoshop (of course not all).
