I'de say that 85% of my tools are Craftsman, but almost ALL my ratchets are Snap-On. Just a better tool, far fewer issues and always works as needed. I only found out after a mechanic buddy gave me an older Snap-On ratchet that was broken for free. I gave it to the local Snap-On guy and he fixed it with a rebuild kit for no charge. Turned out to be one of the best ratchets I've ever used...so I've bought more of them. I tend to buy the industrial models off Ebay, as they run less money than the regular mechanics stuff. They don't have any chrome on them.
Haven't really seen a need yet to have other Snap-On tools yet...but you never know.
