Yeah they don't all do the silver stuff, you can also stress a female so it becomes hermie then you take the pollen and put it on another female (not stressed) : feminized seeds !!!
Stressing doesn't always work though and sometimes you don't have a male. I do think that regular seeds are better though, cause I think fem structures are different. (<my own thought)
Another way to look at it is the forced feminisation of a male seed essentially removes or suppresses the y chromosome and maybe other characteristics of the plant. Some people say that using fem seeds can result in a blander version of the plants because of it.
