Hex drivers: regular vs. ball-tip

[simplechamp]

Which do you prefer?

I have always liked and used the ball-tip style myself. Seems to me like I find plenty of situations where I'm wrenching on my RC's and it's helpful to access a screw at a (slight) angle. I have never noticed them to be more or less likely to strip a screw, and to me it seems like the tips last longer without having as much edge/points to dull. I use Bondhus ball-tip for both my L-keys and drivers.

The reason I ask is because the other day someone needed to borrow my hex drivers and made a comment that the ball-tip were no good, would strip screws too easy, etc.
