The albino and green barbs are very nice indeed.
Fishalicious, the main thing you should be concerned about in deciding is tank size and such. I see from your sig you have a cycling 55
gal. tank. With that, I wouldn't go with any more than 4-5 angels, just because they can get about 6-7 inches in diameter.
I have 4 in my tank now, and they will get pretty big. Then, you have to be concerned about other fish to go along with them. You already have zebra danios and such, but after that, you'd have to be concerned with what else you got.
Angels can seem boring to some,
Angels are anything but boring. They are such the interactive, personal fish. I have one in my tank that I've had about two years, and he comes up to me when I go to the glass. Eats out of my hand, swims beautifully.
So... angels are colorful, bright, active...but require lots of space, touchy fish decisions after you get them.
Barbs...very active, don't require as much space, not as colorful or personable.
All in all, I think if you wanted to house many different species of fish, you should go with the barbs perhaps. If that's not a concern to you, I'd go with the angels. I have angles, rasboras, silver dollars, and clown loaches in my tank, all get along fine.
I think that's about it, haha, have fun deciding!
