It depends on:
1. How badly do you want Satan?
2. How much are you willing to throw at this game?
If 3k coins are all you have... throw those at the SSR guaranteed instead, you only have a 3% chance (and we don't exactly know if anything was changed with this gacha) of getting Satan. Or just save for the future miracle ticket so you actually have a pick. This kind of gacha exists mainly for the whales to MLB their Satan release weapon more so than for people to pull Satan.
