I disagree. As a performer reading notation, yeah, keys with lots of sharps and/or flats are a pain in the butt. However, as a composer, Eb minor is great if you happen to be in the key of Gb, because it's the relative minor. Anyway, the musicians in the 18th and 19th centuries had a lot to say about aesthetics and the "color" of each key, and Eb minor was generally referred to as one of the most striking of the minor keys. Schubart had some interesting things to say about it. Also, Eb minor is used to great effect in heavy metal and rock songs all the time -- it's very easy to play on a guitar. And you obviously have some singing background, so you should know that with the moveable tonic style of singing it's not difficult for singers either.
