Do artifical egg clusters, i.e. goey-bobs, smelly jelly eggs, etc. work as well as the real thing when float fishing? If the water has poor visibility would I be better off using fake eggs over a jig?

I'm new to jig fishing, yes I plan on attending the Jan 8 seminar at 3-rivers, and no I don't have any real eggs in the freezer yet to use. Mostly curious if the fake eggs are any good.
