Yes I have both. I have about 3/2 as much or maybe 2 times as much UG as HC. But the HC I have is very healthy. And I have a friend who's willing to sell me a nice amount if I decide to go that route.
Maybe UG with HC tucked into crevices? Or invert that? I'm trying to keep it simple, like less than 3 plants total, maybe 2 or even 1. lol
