I prefer
Aaron because it looks familiar and correct and nicer.
Aaron is like that nice kid who lives next door and
Aron is like that obnoxious kid who lives down the street and you hate walking past his house because he might throw stuff at you. Plus it looks like A-Ron, and I don't like the
Ron part, look or sound-wise.
Aaron is a nice soothing blue with a strong red at the end, and
Aron is just bright red but the white in the middle sticks out a lot more.
I'm surprised that
Aaron never made the Top 20 since it seemed to be fairly common in my age group (mid 20s now). I can think of at least 3 Aarons I went to school with, and one
Aron. Also we had a pastor at our church named
Aaron (he's in his mid 30s I think). I would say
Aaron is the type of name that might go up and down in popularity, but it's a pretty strong Biblical name with a fairly solid history of use, so I don't think it will ever change popularity any giant amount.
I don't think the extra A is unnecessary at all. That's just the way it's spelled. There are a few other Biblical names with double As.
Aron doesn't look foreign, it just looks wrong and like someone wanted to spell
Aaron differently. But by taking out that nice soft second A it visually becomes very sharp and pointy and thus the obnoxious image it gives me.
Yes, I pronounce
Aaron and
Erin the same.
