Dude you nailed it! GSP is one of my absolute favorite and people treat it like garbage. I think it’s one of the most beautiful corals out there. The way it waves in the flow is amazing. I’m trying to cover the whole back of my background with it. It’s stunning to say the least. No idea why people hate them and give them such a bad rep.I do too. I'm relatively new to the hobby (less than a year), but this hobby has some really bougie cliques in it.
To me the value is "How much does this make me feel like the ocean? How objectively pretty is it?"
A lot of people seem to assign aesthetic value to the rarity. I've seen some very rare stuff that is ugly AF to me. GSP is still my favorite coral. It is objectively beautiful. Bold colors, and lots of movement. It looks like grass from a fantasy painting. But because it's so common and easy, a lot of people treat it like it's garbage.
