On bosses like Drestagath where you can't really build up good stacks, going for the PSCD is the safer play, as it's always going to be giving you something. The Coral can still shine on encounters like Ilgynoth, Carapace, & N'zoth, but the difference between it & the PSCD is smaller on such bosses, while also being more of a pain to use. It's still entirely worth it if your group needs that extra consistent damage in the execute phase, though.
I'd still try get a Coral as it's only 30 mins of farm on a weekly basis. Just have a look at logs before hand to see where it sees the most use & where it doesn't - it's typically a good indicator.
