My vote would not be on the Microfire for two reasons, the price and the color temperature. I purchased mine when it first became available and for around $375. Although it's a handy size and thus far has been reliable, it's not inexpensive at $500+. I could better justify the price if it was a 4300K bulb but instead it's a very blue 7000K bulb. Honestly, I think the Tactical HID is a better value at around $200. If you're prepared to spend $500+ on a Microfire with blue beam I can sincerely recommend that you instead purchase the LED powered Olight SR-90. It's really a better value and has the better all-around beam.
Alternately, a Polarion X1 can be had for around $1200 used if you keep your eyes open and they really are magnitudes better than any other light I can thing of at that price, or pure retail.
