Replying to Fks 120 or 140

I'm debating on whether to get the fks 120 or the fks 140. This may seem kind of snobby but I really hate the orange on the 140's, enough to be debating whether to get the 120 or 140. My question is how much more durable are the 140's than the 120's. Is it enough of a difference for me to put aside my disliking for the orange and buy the 140's or should I buy the black 120's. ***I know there are black 140's but I can't find them anywhere***
