The Snap-on hard handles if you use them hard everyday. If not then the soft grip. Most mechanics I've spoken to, don't like any of the soft grip tools because after awhile the handles deteriorate poorly with oils, grease, cleansers and dirt. The rubber gets worn usually in a year or two. Where-as the hard handles wear well over a long period of time. I've had my hard plastic handled ratcheting screwdriver for over 12 years and is still in great shape, I use it so much that the Snap-on logo is almost worn off. I've had the same ratcheting screwdriver in a soft grip now for just over a year and barely use it, it just doesn't feel as nice as their hard plastic handles. It's really personal preference, but I think the Snap-on hard plastic handles have the best ergonomics, best balance and their tips are hard to beat. This all depends on the size of your hands and how you hold a screwdriver, like I said, personal preference. The only downside is the cost, I think the 8 piece set in soft grip or hard handle is roughly, $125-$135 US. And they have many more sizes and configurations, especially with shank length in torx and posidrive as well. I have between several hundred to a thousand dollars in Snap-on hard handle screwdrivers and there aren't many, maybe one drawer or a drawer and a half. IMO, when it comes to screwdrivers, the Snap-on hard handles are the best.

But like I've always said, if you're not earning a living with your tools, then Snap-on pricing is very hard to justify. Those Craftsman pros look well made, the next time I'm in the US or if a friend of mine is going, I'll be sure to pick up a set of them.
