Butterflyfish vs dwarf angels? Which is less " reef safe "?

Currently I have a 75 gallon reef tank with a whole bunch of LPS, softies, RBT anemone, 2 urchins and an orange sea star. I've got a couple of fish left on my wish list and one of them is a flame angel. I realize sometimes you get flames that reek havoc in reef tanks but I truly believe its worth the risk. I've also always loved the beauty of the yellow longnose butterfly, but have been told throughout the years that there is pretty much a 100% chance of them destroying your reef tank :-/ so I eventually gave up on my dream of keeping one in my tank, however the other day a pack of Fireworms killed my yellow wrasse while he was asleep so I've been looking to " hire " a new yellow fish for the tank, and I keep leaning towards a longnose butterfly, and after reading LOADS of info on them, they seem to be just as risky as a dwarf angel, which I'm willing to risk. I realize that LNB will eat fan worms/feather dusters and have been known to do damage to clams but I don't plan on ever keeping either of those animals in the tank. So my Q is, are YLB just as " reef safe " as flame angels?? Thanks everybody, and I'd prefer first hand experiences or tips. None of that " well the book says........blah blah blah "thanks

 

10 fish is probably pushing your limit what is your equipment and setup.

 

Butterfly fish are not reef safe although some ppl have had luck with the copperband butterfly fish

 

My 75 has a 20-25 gallon sump/refugium, with a basketball sized ball of cheato morpha and a coralife super skimmer-125. NEVER have I seen a single fish even nip at another, everyone gets along perfectly, even my tomini loves to swim around with my possum wrasse and leopard wrasse who share his section of rockwork. I aquascaped my tank with the right side being occupied by most of the rock work, and the left side is pretty much all open swimming space ( besides one small rock structure ). My nitrates are 0 also.

P.S. I also run a 4 inch deep sand bed in the display
