I had the same experience with my Craftsman 3/8 drive first year living at the lake. My wife was helping me put in a dock, a bee buzzed by, she took a swing with the socket wrench and the deepwell 9/16 drive went flying off and was lost in the silt on the lake bottom. It was part of an extra long set and it's replacement is a good 3/4" shorter.

Your experience speaks to my point. Snap-on, Mac, SK tools are standardly longer and thinner and nice and smooth compared to Craftsman tools. Since I'm constantly designing parts when there is a certain area I have to put a wrench or socket on the part for installation or adjustment I typically check tools to see if what I'm planning works for the installer. High end sockets are thinner wall, at least as strong and take less room to design clearances around therefore I tend to favor them.
My Proto crescent wrenches have a little snap like feature to them that has meant they keep the space constant on the adjustable setting as I take the wrench off to make the next twist. None of that annoying resetting or slipping each time you have to get on the nut.
Since Craftsman have a lifetime warranty put one on a 1/2-13 grade 8 bolt and nut and tighten. It used to be you'd find you will break the socket at someplace between 75 and 90 foot pounds. You won't do that with Snap-on or SK. Maybe it's better now... but it's 28 miles to Sears from here so I don't ask my Craftsman tools for that much. If you are just putzing around like me at home that's no big deal but if you are paid as a mechanic by what you fix you have no time to run out to Sears and get another socket that still won't take the 120 ft-lbs you need on the camshaft pulley on a Volvo.
I've been buying the Allen brand because they feel good and are available in the hardware store 3 miles from here. All these brands have lifetime warranty it just depends what you're asking your tools to do.
Make sure you don't ask something cheap to do more than you ask. It hurts and bleeds like hell when your wrench lets go and you hit your hand/arm.
