If my name was Maxx, I’d want it to be spelled like that, with the second “x.” Then, if I met someone with the same name, say if somebody said, “Hey, Maxx, his name is Max too,”–as people do sometimes, with any manner of name–I could say, “How many “x”s you got?” If he only had one, I would always have that over him. It would be a mental thing, and if we competed against each other it would give me an edge.
If he did, however, happen to have two, it would still be a tie, and the two of us could go off into the world in search of all of those other guys who didn’t have the extra consonant. When we’d find them, we’d ask them if they wanted to play ping pong or something.
On the very off chance that he had three “x”s, that wouldn’t even be of concern to me. I mean, really, he might have more “x”s, but you gotta know how weird that would be.
So, I guess I’m glad I have a name that everybody spells the same.

As someone whose name is spelled both Matthias and Mathias amongst other gentlemen, I must confess that I do somewhat have this mindset. There aren’t many examples of guys with the same name as myself, and the only one I’ve met personally, while having the same spelling (and we both look somewhat alike on top of that), pronounces his name differently. So, I can’t really say that I have had much luck with this comparing / contrasting names.
Also, I will admit that an extra “t” doesn’t have as much oomph to it as an extra “x”. “X” has some quality to it that just rocks.
It does, doesn’t it? I’ve always had the idea that I’d be cooler if my name was something like Rex.
