a typical bag of premium pellet should produce about a half a coffee can of ash, most of this will be in the front end a lesser percentage gets carried through the system, some make a bit more some a bit less.
best thing i can advise is "try before you buy" get a bag or two of each, run them and compare , but do a good cleaning between tests so you dont poison the data by testing with a dirty stove
