For example, I though "j" would be decent letter but many people seem to hear "Juliet" as "India".  Don't know why they make that confusion, but they do.  So, which letters are best recognized and less confused?

I can tell you that for reasons completely unknown to me, people (both DX and domestic) seem to copy the "I" in my call as "R", whether I use 
phonetics or not.
