I have a few rainbow cyphastreas... and I do have the 4 color pectina. Honestly, it looked like poop but its starting to get nicer and its growing on me. It's a cornbred coral so the fact that it looked like poop in person doesn't surprise me. I paid way too much for it considering its size a year ago but its up to 10 eyes or so. The space invader is just sooo BRIGHT that it really stands out in comparison. The green is vivid and it has a true yellow that is super bright... as you know a true yellow is prolly the hardest color to find for a reef tank. If you ever make it over here, I do have them side by side so you can compare them... I'm fairly certain you'd pick the space invader as well
