EasyOff and other oven cleaners will do the job-once.  A big advantage of SuperClean over oven cleaners is that you spray the oven cleaner, and that's it for that batch.  With SuperClean, you can fill a jar and use a batch over and over.

SuperClean is also not quite as caustic as EasyOff.  You should have good ventilation with either product, but EasyOff is definitely more volatile and more caustic than SuperClean.  SuperClean doesn't fill my cellar with fumes as EasyOff will. It's interesting because the active ingredient in both is lye.

Using one or the other really isn't related to the subject you want to build.
