I'm not nearly as experienced as some of these guys, but have been doing a lot of research as my interest in NPS has been gaining. There are some NPS that you can get away with a concentrated feeding while others will need that continuous supply of food. I have purple menella gorgonian that I target feed a cocktail of frozen cylop-eeze, reef roids, and fauna marin to 1x or 2x a day... turn off return and all circulation pumps. After 10 min, I turn the circulation pumps back on but leave the return off for at least 30 mins... usually more.
So far, so good. I've had him for 3 months and he grown probably an inch and is open 90% of the time. Of course, 6 months and a year are better marks for judgement of how it's fairs. I do want to try some other NPS gorgs such as Diodogorgia as it seems they'll do ok with the concentrated target feedings. I wouldn't dare try a blueberry gorgonian or something like a carnation coral. My sun corals have been relatively easy to care for as well... just have to make sure the fish don't steal the mysis away, but I have figured out a routine for myself that works.
So, my personal opinion is that it depends what you are wanting to keep.
