It's going to be personal choice, both are good but they have a different sound, there are also fans of both on the site so there will be an even number picking each. Just to confuse you more have you checked out the Yamaha HS50M and the HS80M monitors, I haven't got any but I had a listen to the HS80M at a show and really liked them.
thanks for the feedback...
i was thinking about going all out and getting the new krk expose they are lovely speakers i listened through them once and they are amazing
