The run times are about the same.It also doesnt get any hotter than the mm 8xl combo.The only way you can tell the difference in performance is if you run them side by side.If you take them out seperately they feel the same.The mm is nice because you can program w/laptop but once your done you really never change anything.I got my hv for 300 and my buddys total was around 215,so if it came down to money the mm is the best combo for price only.
