If I were you, I'd keep a very healthy supply of BOTH around. Seriously jl3140 pretty much summed it up the overwhelming majority of people never have an issue with Crystal Clear and the Essential Plastic is a very good plastic that is a little more forgiving for the beginner. Both need care when it comes to mixing in the container before drawing out to heat EACH time.
be aware the essential series plastisol does not float unless you add alot of softener.
