I don't think they will only eat pellets. I know of quite a few that would not eat anything but flakes. But pellets are not as messy and they are much easier to feed in a certain dosage - 3 pellets vs. say, 3 flakes... pellets are all pretty much the same size and flakes are many different sizes. This obviously doesn't matter as much if you are feeding a group of fish, especially like, a sorority, because it's nearly impossible to feed each and every one exactly X amount of pellets.
Flakes also decompose faster and break down if they remain uneaten. Also not really an issue if you've got a tank such as a sorority because they don't really let food go uneaten.
I guess one thing that I like about my NLS pellets more than any other food is that they do not decompose like any other food type I have seen. Pellets such as Omega One get waterlogged and lighten in color, grow in size, and if you've ever attempted to siphon a sunken pellet like that, it breaks up into a million itty bitty pieces. NLS stays whole, doesn't lighten in color, and if you try to siphon it out even if it's been sitting at the bottom of the tank, it still stays in one piece and makes clean up a lot easier.
I know that this is mostly a personal preference and in certain cases, like if you have live plants and don't really need to siphon the gravel, it doesn't matter as much, but there are many people who think that pellets are better than flakes. I have seen some who believe that flakes cause bloating issues more often, but some fish bloat easier than others and I'm not really sure of the truth behind that.
