The 940 family is a great family of knives. I personally have a 940 which I own , and love dearly. I like to know more about someone, before I recommend a knife to them, but here's some things to consider:
If you're worried about aesthetics, and don't like scratches, the 940 family is not for you. The anodized aluminum scales will get scratched. The only exception here is the Carbon fiber 94X knife they have. I don't know how CF scales show wear though.
Is the blade shape good for you? I assume you don't do a lot of slicing then. Personally, I like to have knives that do, since I use mine a lot at lunch, camping, etc.
Going back to the handle/scales: Do you find yourself in wet/oily conditions? The reason I say this is the 940 family knives aren't the grippiest knives Benchmade makes.
COST: What is your budget?
Here's a few Benchmades I own and love:
940 - solid choice. Compact, with a lengthy blade
Gripitilian - a little beefier, more affordable, and will last forever. Don't be fooled by people saying they don't like the scales. Fully customizable: Steel, Blade, Colors, etc.
Barrage Family - Easily de-assisted, so you still get the awesome axis lock flavour. Slim, yet bigger handle. Two blade shapes and customizable scales, blade steel, colors.
I would also look at the Axis Strykers, as they're excellent too (I have handled them extensively).
If you would like a photo comparison, let me know. Here's what I've got

940 scratches just taking them out of my jeans pocket, because of that stupid little metal snap on jeans near the pocket.
