I like [name_f]Leona[/name_f] a bit, & [name_m]Leo[/name_m] a lot, but [name_m]Leon[/name_m]… Not so much. 
If I was AMAB my mom wanted to name me [name_m]Levon[/name_m], though. 
I say it LEE-awn, not either of the ways you said, which is how I’ve heard it pronounced
I like [name_m]Leon[/name_m], it is like [name_m]Leo[/name_m] but more serious. Sounds like the name of an intelligent and kind person.
I just started liking this name and added it to my list. I say it as [name_u]Lee[/name_u]-awn. I really like [name_m]Levon[/name_m] too!
