I like it and I much prefers the spelling of
Louis.
The only irritation is when other folks tend to believe that Lou-ee is the only or actual pronunciation. Ugh...
Louis is pronounced both ways. Just a matter of where you live.
In my opinion:
Lewis isnt bad. It just reminds me that its often used as a generic surname. Plus, I think that the spelling of
Louis looks more handsome\attractive (:
