I'll bet you can find a thread with someone saying they had a bad experience with just about every screwdriver brand out there. Some tips will deform, some will chip and crack. It also has a lot to do with the screw. Some screws are very hard and strong, others are weak. Finding the right size screwdriver for a particular screw is critical. That's why manufacturers make so many different sizes. Making money isn't the only reason there are so many. I know you can often 'get away' with using the wrong size but if you want to get the maximum life out of the screwdriver it helps to use the right one for the job. That being said, Felo and Wera have worked out quite well for me so far.
This part is slightly OT but...
I bought a curtain rod recently which came with some small screws. I used one of my Klein screwdrivers to drive the screws through the drywall and into the studs as I did not need/could not use the included wall anchors. Guess what? ALL of the screws snapped in half while trying to drive them in! Martha Stewart brand curtain rods are EXTREMELY low quality. Yeah, the one I picked out looks pretty good but the screws they included were garbage. The rod and brackets themselves are also not for heavy duty usage but whatever. The only other Martha Stewart product I used was some paint, which my brother actually bought for some odd reason. It was peeling off the wall a week later! Yes, I used primer under it. Long story short, if you buy one of these Martha Stewart curtain rods from Home Depot, make sure you pick up some good 2" black drywall screws. You will need them if you want a quality installation.
Oh yeah and my 10 year old Klein driver didn't take any damage
