Just keep in mind that both Jamba and EMA have gone through a fair bit of change since the 8.x patches hit. EMA is also a new fork of Jamba, so give it a bit for Ebony to wrangle it into shape. Ultimately, though, the "best" is the one you can make work for you. The API changes destabilized a BUNCH of addons, and some are still really struggling to not just asplode, catch on fire, and burn the house down (see most of the auction house addons like TSM).
