I think it depends on where you get your neons....sometimes they do alright, other times they do just randomly die off for no reason. Sometimes they can also be a little nippy with bettas, even in a proper school....and other times a betta will go after them, even eat them if they'll fit in his/her mouth.
So neons are kind of a hit-or-miss on a couple different levels. xD
Cardinals are indeed a much more hardy and just as lovely alternative.....but not for a 3 gallon of course, just making that clear for the OP. xD Actually I do believe Cardinals get a little larger then neons though....probably would want a 15-20 gallon for a proper school of them long-term.
