Nope, its not. They just never die from the move lol. So even if you hit with it you're still going to be punished for it, and if you miss it'll be an even bigger punishment. So against heavies its not the ideal move.Rest isn't really good against heavys....
On the other hand, its wonderful against light weights and it makes it harder for people to counterpick you since Jigglypuff's bad stages would be levels that have short ceilings. With shorter ceilings means a quicker rest.
