Even craftsman does not have or need a pass/fail thread.
Funny, I have thought about this several times but really, what is new in Sears that you would give a pass? There's no need for a pass/fail thread since we have a few individual threads people have found gems still available at sears, but typically if it's newer than 1995 from Sears it's a fail, with a few categoric exceptions like air tools (some) compressors (some) screwdrivers, etc.
You won't get a consensus about any brand here at GJ. I think I'm somewhat qualified to talk on Kobalt since I have owned several of each generation of their tools. I have used them semi-pro as well as plenty of DIY use. For me, Lowe's is more convenient than Sears or Advance, and back when GW first came out Kobalt was cheaper so I chose those.
I wouldn't buy a Kobalt hammer, tape measure, I would be really picky about pliers (some have been ok but I have plenty that weren't), anything sharp, screwdrivers aren't consistent enough to call them good; I have got some really good and really terrible ones. The exception is their 8-in-1 precision screwdriver is really good, I especially like they have a torx version most others with that style don't.
The double drive is a great screwdriver. Now that there's plenty of brands that have it you don't have to go Kobalt if you don't want. The metal housing one is better than the newer plastic version.
Sockets of any generation you are going to get basically the same thing; 'tallish' shallows in 6 pt, deeps in 12 pt, decent quality on both. Sure the Williams are better than the others but other than the last gen Danaher USA, which were all 12 pt except the 1/4" standard depth sets, they are decent sockets.
The standard/shallow sockets are almost as tall as my GW mid depth, and taller than many other sockets I have seen. The deep sockets are fully broached. depending on your use, might be good or bad for all these factors. Sometimes if you are trying to put a ratchet where a wrench should go, these aren't going to get there. Before I had ratcheting wrenches it was very frustrating.
I will also add this though, having a lot of Kobalt 12pt sockets is what's fueling my desire to own all 6 pt sockets in all drives and I have been upgrading my socket drawer quite a bit recently. Generally I would say GW sockets are an upgrade from Kobalt.
Ratchets range in quality and comfort. What might be bad for me might be exactly what you want but in general, the tooth count isn't very high on most of them. 36 is the norm some are 72. The 3/8 gimball style ratchet was my go to ratchet for a long time, but side by side it is not as good as the HF that's basically the same. The HF also has a quick disconnect, something a lot of Kobalt ratchets lack.
I know I'm going to catch some **** for this. The wrenches, being 12pt for all generations of the taiwan built ones, are decent. Both ends have held up in my uses. I didn't like the feel of the wide flat Williams designed ones, but they were good on the business end also. I do wish Kobalt made 6pt wrenches but again that's up to your preferences. I'd say they're at least as good if not better than the last gen Cman USA 12 pt combos. I have 6 pt CM RP USA NOS now but I have used those Kobalts plenty and still keep them.
I haven't used the ratcheting wrenches from kobalt, any generation. They are way overpriced (or I don't see the value in their price point). Same with the 'x grip' or whatever they're called that bend in the middle. Many newer Kobalt tools have been gimmicky but then I bet you already knew that.
