I've had both. The 11 just was not comfortable for my medium-sized hands no matter what I did. I traded it for a 14 which I still have. I also got another 14, I liked it so much. I use a set of TKC aftermarket scales on mine with a short lanyard tied on. With those scales and lanyard I have no problem with it being comfortable. The scales also changed the balance just enough to make it almost neutral. With the lanyard, it balances very slightly to the handle end. Made all the difference in the world. I don't like small knives that are blade-heavy.
That's the best I can tell you. The knives are identical except for the handles so that's where you're gonna have to make your decision
