Hi Mik_101, I'm sorry if I came across harshly, it's not my intent. I just want you to be able to get all that you can out of this hobby - because there tends to be a LOT of frustration that we have to suffer just as much as all the good things; so if I can help someone avoid some of that frustration, I want to do so, because it always makes me sad to see someone quit because the hobby got overwhelming for them.
If I was in your position, I would try a flame angel. Particularly if you can find one that was collected in Hawaii because the colours are out of this world (the Hawaiian flames tend to have much more brilliant reds to them, as opposed to orange and yellows, and the striking red colour creates a bold contrast to the blues on their tails). They are all pretty however, not just the Hawaiians.
I'm afraid I can't offer much on the others you've listed as I have no experience with most of those (I've only ever kept a potter's, but I have friends who have flames and I've looked at them a lot
).
Here is a good site dedicated to info on the pygmy angels:
www.centropyge.net
It lists the angels by species and gives you some to-the-point info. For example, here is the page on flame angels:
