I am also a serial fish food tester, I've had great luck with all the new varieties coming out made with black soldier fly larvae, with fluval bug bites cichlid formula being my south american community's favorite food.
My most recent batch was northfin and I expected the bug pro wafers to be the favorite but their 1 mm veggie pellets are my cory's current favorite, it sinks to the substrate much faster than other pellets so I don't have to worry about tetras getting too much.
I always go back to extreme pellets at least once a week though, everything will eat it even if it's not the favorite.
