It's chavy and immature
I am not a fan of either name. Mason is too last name for me and it's a town near here. I just think of blue jeans when i see Levi.
Tacky and try-hard.
Very nice and will age well, not some silly name for a 59 year old man.
Where I live in UK it is a common Jewish name.
Not fond of Mason, but Levi I like.
Nice. Very masculine.
I love Levi.
If you love Mason Levi it's fine.
The parents are the only people that need to love the name.
It's not hard to say, it flows.
"Mason" is an occupational surname - terrible as a first name. If Mason is a family name, move it to the middle "Levi Mason so-and-so."
I'd think you live in a trailer.
