I have FSA compact cranks (an energy on my steel and sl-K carbon on the other) and so far have had no issues with them. The only trouble I have with all compact cranks is it is tricky to mount the FD so you don't get intermittent chain drop onto the BB shell when going from small to big. Keeping the FD cage as low as possible just shy of hitting the large ring and perfectly parallel to the chain on the highest gear seems to work.
