Not very familiar with these two, but the more expensive one has EMG pick ups, (better for metal) and the other one has humbuckers which will give you a fairly warm sound. also the red one has a flame maple top and the other one has a quilted maple top. What kinda music do you play? be easier to advise that way..

Nope, but the EMG's are more suited for metal. They're active pickups though, so supposedly if you play through a tube amp you'll get the full effect of the pickups. Never owned a guitar with EMG's though so I can comment. The humbuckers will get good distortion too however, and play cleans a little nicer as well. Not sure how well the cleans on the EMG's are, I would imagine they aren't the greatest ever, maybe someone else knows.
