which bag??

The lockit is just more sophisticated and elegant in my opinion, but the neverfull is an anytime anywhere kinda bag.

I would tend towards the lockit if you have a dressier workplace and I just like it better.
 
What will you be using the bag for? They are two very different bags. I'd get the lockit if you want a more sophisticated, structured look, but the Neverfull GM if you want something more loose and casual. It also fits A LOT so I use it for school!
