IMHO, alFiqh alManhaji is a good text for teaching Shafi'e fiqh, ie good for public to learn fiqh WITH a qualified teacher. In Malaysia, I think it is becoming one of the favourite text for teaching shafie fiqh in masajid in Malaysia. However, for people who wants to delve in-depth, may find alFiqh alManhaji NOT deep enough in discussing the masa'il. Wallaahu a'lam.
