As we slowly sink into the Craftsman vs Snap on quagmire again, has the month passed. The real truth is each has its place. As stated before each line has various models in different price points for different users. So starting this way.
The Craftsman Home series, Name says it all, for the limited use DIYer or something to store those things you do not need often at a very low price.
Craftsman Quiet Glide, Roller Bearing, Grip Latch Series. Will work for most DIYers to Moderate professional. By moderate professional meaning can live with the load limits of the drawers, maintain the drawers and do not move them around to much. I have seen many of these last for a 1/2 to a full career for many of my friends. You do not do things like shove them around a rough farm shop floor with bobcats, etc to them. Rolling 1,000 lbs is not easy. We do use them many places due to value and ease of purchasing, going to Sears take the pickup and get one. The minimum for a busy shop with not many tools required. You can use less, but will not provide long term reliability. Each of the boxes listed above has a higher price and caster bearing weight.
Sears Pro a step below the truck lines, but not a bad box. It depends on how you use it, what you put in it, will stand pushing around rough farm shops with a bobcat if you are careful, ie use a protetive mat, close the drawers, do not use it as a stairs, push it into walls. When properly set up with dual slides will hold about everything you can pile into it. If stationary, properly orgainized, greased and load limits understood, will last for years and for most a career. Priced less than the truck lines and easier to find. Still not a status symbol. Minimum for busy shop with lots of tools required. Again you can use less, but expect a shorter life.
The truck lines, pick your poison, price, and status level. Still they are heavier and if good used ones are available can be a better option than the Craftsman Pro. Still can be more expensive so you have to shop carefully. Again expect to run into 2 - 3 lines at different quality. They start from a level above Craftsman Pro and go to a point you can abuse them like I described and they easily survive. They will take more abuse, but, again at a cost. It comes down to will survive your career, but if you are the type of person that buys and sells every few years it can get very pricy. Service depends on your dealer, which can be marvelous to terrible. Still in rough use can last long enough to be used at a person's funeral. Expensive enough and with payments and interest you can have years of payments.
So look at where you work, what they use, because the type of work, amount of tools used and required, will really dictate how much you need to invest. For most it is less than we spend. ie how often are tools taken out, how many, how many are stored, how heavy are they, how hard are drawers slammed. If these are on the low end, then a lower priced one will survive well, if on the high end look up.
To compare one to another is apples to oranges. It is up to you to see what you spend.
