Derailleur adjustment with compact crank

[7rider]

I know in some of the crank reviews I've been reading (fsa gossamers), people have claimed that buying shimano compact cranks completely solved any problems they had with tuning the compact or the chain going off the cranks...

That was my experience.
FSA (SLK) crank + Shimano FD = chain off the crank upon shifting (okay..not CONSTANTLY...but often).
Shimano crank + Shimano FD = no shifting issues.
Cannot speak to FSA crank + FSA FD.
