The new EFI is extremely reliable, but the service and repair cost over the life of the bike is potentially much higher with EFI, not that much of a factor if you intend to keep the bike for a year or two, but the longer you keep it the more of a factor.
It also makes you much more dependent on the dealer. Again, not that much of a problem in Germany as here, other then the cost.
As far as performance, the difference from EFI to carb is less then the difference from one bike to the next. If you could find two otherwise identical bikes the injected bike would be a little better then the carb bike as they come out of the box, but with about $10.00 in jets you can make the carb bike outperform the EFI, and gravity will always be more reliable then electronics.
I'm not sure about the FatBoy, but the EFI touring bikes are geared different in Europe then here, and again totally stock the EFI bikes lose even the minor advantage.
