Yes its one of the better known mechanisms but to be fair most are much of a muchness, its how many points it locks on and in what way!
Doors, generally should have at least 2 hooks, 4 would be better though, should have at least 2 roller cams/mushrooms and top and bottom shootbolts, i didn't include the middle latch and deadbolt as all mechs have them.
Windows, all depends on the length or height of the opener, this governs how many roller cams or mushrooms you have, obviously the more the merrier, shootbolts at each end are a must also
