Agreeing with this. I don't see the "ugly phase" as a bad thing, just part of the maturation process. I'm going with all live rock this time again, but even there, there are some stages as your tank becomes mature and you become familiar with it. Nothing is 100% perfect 100% of the time, especially in nature.IMO the ugly stage is something the ROCK goes through. Not the tank. (To a certain extent the sand, which is after all just lots of tiny rocks).
So if you started the tank with all established post-uglys rock? Sure, sure, it's not going to go through those stages; whatever. But new rock added to this system will. I just saw this firsthand - I upgraded from a 75 gallon to 230 gallons in December; ended up with about 2/3rds new dry rock and 1/3rd established 10+ year old live rock from the old system. All of the new rock went through the ugly cycle. Bone white -> Neon Green -> Diatom Brown -> that funky mottled appearance of mature rock, you know what I mean.
Kinda wish the neon green phase lasted longer. It looks kinda neat.
I think it often comes down to a difference between seeing your tank as as static work of art versus an ecosystem that you get to work with. Gardens also go through "ugly stages", pests, weeds, etc and you have to figure out how to manage them. A mature garden that is grown in well is easier to maintain than a newer garden with plenty of empty spaces for weeds to encroach and pests to take advantage of, but for gardeners there is enjoyment from spending time in the garden working through those stages, not just the end result.
Our tanks are more like gardens than paintings.
