I cast my original vote for the rams because you said that you were planning on getting neons and they generally don't mix with angels very well. With the neons not a factor, I would definitely choose the angels. I have 4 in my 75 gallon and they are truely beautiful fish and you can always see them. I haven't had blue rams before (although I still may put some in that same tank) but I understand that they stay hidden quite a bit so you maybe won't see them as often.
