I saw this: the power of the FM9 is more or less half of the FX III, i was thinking that the gap was less.....i will probably go with the FX III.
The FM9 is no slouch, and the difference, besides the raw computing power, isn't that much, especially with the latest (today's) release of the new FM9 firmware. Only if you need something that's missing would you notice because the FM9 sounds amazing… as does the FM3.
I'd pick purely based on the convenience of your situation. The FM9 on a desk takes up about the same amount of space as the FX3, but, the FX3 can be rack mounted, either on a desk stand, or to sit next to the desk in a separate desk, or a small unit for the FX3 only. Mine sits beside my desk on top of a small chest of drawers and is in a little road case for when I get a wild hair and want to take it with me somewhere. The FM units definitely shine for travel as I have dedicated bags for them.
I recommend the FC12 if you go with the FX3. Even at home it is convenient.
