I think instead of trying to decide based on "bike for the buck" you should've ridden both before deciding since they both ride very differently. The Epic is more of a XC race bike where the SJ has more travel and can take bigger hits.
Components wise, the SJ Elite is a better deal but the Epic has a brand new frame design which is probably lighter. It also has a rear shock with Brain which some people would think makes the Epic Comp a better choice.
