I couldn't agree more with this statement. I have a Fuji kit and a Canon kit. I use the Canons for Weddings or any paid job where I can't afford to miss a shot. I use the Fujis for my walkaround/landscape/personal photography. I still miss shots with the Canons, but usually it's because I'm not quick enough, not because the camera isn't quick enough. When I shoot with the Fujis, it always seems like they have a hard time keeping up, which diverts my attention off my subjects and ultimately frustrates me. I know there are folks out there who use Fujis in a professional capacity, but I cannot. And the trade-off in weight savings doesn't justify all the other 'quirks' I have to put up with. I need my professional equipment to be responsive and dependable. I have enough to worry about on a shoot without the stress of batteries dying suddenly, or the camera freezing up, or overheating because I've used it for hours on end, or the autofocus causing me to miss shots. I like Fujis for what they are, but they have a long way to go to catch up to the Canikons of the world - even with the latest advancements (XPro2, etc).
It's for that reason that I don't think it's even fair to try compare the two, or expect that Fujis should be as good as a pro DSLR. Maybe one day they will be to the point that they can be compared, but for now they are not even in the same category.
