way too subjective, all you'll get are fanboy opinions... "this one is best", "no - this one is"
look up the manufactures websites for any board you want to consider, check their specs against other equivalent boards. make sure you compare apples with apples.
also check out the many review sites that exist for this sort of thing.
the last thing you want is someone saying Brand XYZ is best, you then buy it and 6 months later it dies and you saying "well that was crap, thanks for that!"
