I have 2 snap ons and a Mac they both work really well, I use them everyday on very expensive componets.. I have used a Craftsman a few times and it also worked well although I didnt really like the feel of it(plastic handle vs knurled steel) depending on your intended usage spend the extra money and get a quality peice..
Being as this is what I do for a living, is calibrate test equipment. Here is a profesional opinion. CDI makes good wrenches that stay fairly accurate over extended period of time. Snap on is really good quality stuff. Craftsman will warranty them as long as they are BROKEN. But they will not warranty them if they fall out of calibration.(being that it is a wearable knuckle or a spring that wears out) But if it breaks as per say any other craftsman might break you can force the issue and get them replaced. Did it a bunch for the Air Force. If you drop it..which I know you will, it will be out of spec, 9 times out of 10.
I have had craftsman replace several torque wrenches that were definitly older than 90 days. Like I said if you force the issue of manufacturers defect and not accuracy or calibration issues then they will usually replace them. Example-handle breaks or locks up.
by far the snap-on are the best that I have had, the Craftsman are nice though for home owner use. The reason there isnt the lifetime warrenty is if you break if you were miss handleing the tool, I.E. you didnt use it for its intent, its build to handle what its torque range is marked for.
I've got a Snap on that I bought many years ago (about 10) and I've built a couple of engines with it and tourqued a bunch of wheels. Allways seems like it's good but I also wanted to get it recalibrated and went to a Snap on truck and the guy wanted like $150 to calibrate it I decided I'm not gonna worry until it's time to build another engine.

Clickers are untrustworthy. I also had a dial type that went
slowly insane. A beam type, though, is not easily fooled or
hurt. Only downside is lack of ratchet action on the old
school beam torque wrenches. That hurts in tight places.
If you have a clicker then you can use a beam wrench to
check cal in a rough sort of way.
