OK....the best mechanics tool set is the one that gets the job done right and easily. I am sixty years old and was first a professional mechanic before I was a Jeeper. Sure Snap-On has better quality when it comes to metal content and fabrication...so does other tool companies like Matco and MAC tools. BUT, not every company makes the same style wrenches as an example. You buy the tool that can fit the situation. If you need narrow jaws on your wrench and Matco is selling the size you need,,,,you buy it! If you shave down your wrenches to make it fit the job, you lose strength! That results in damaged hands. I,definitely, would not buy anything made in China or Asia. Their metal fabrication is inferior in composition.
When I was a youngster, it was a smart thing to find a master mechanic and let him be your god father in the trade. Jeep forums are good but limited.
