Ok so I would tell you that I personally had no difference in caring for any coral I have that was in the Soft or LPS category.
With that said, there are differences in the corals as far as the light and current they like but if you pay attention to those 2 things and keep your water clean you "should" be ok with just about anything in those categories.
I will stress that you "HAVE" to read the corals requirements but you can feel free to just poke around those category or corals and know that almost and I say that with a little caution, almost anything you find in those categories will be easy to take care of.
I have easy to care for mushrooms that if placed in the wrong are do not open as much so that is why I say to watch the placement and waterflow and light requirements closely.
