If you are looking for a deal, Proto. Lots of availability through tons of online retailers so coupons and discounts are plenty. I love my Protos. All my SAE sockets at home are Protos. The larger sizes and the deeps get heavy though. They offer a ton of options for sizing in all drive sizes too which is why I use them a lot.
US alternative would be Wright. I was down on them initially (I apologize Wright Tool, I was a fool) but now that I’ve been using them at work, I cannot recommend them enough. Nice weight, beautiful chrome, excellent stamping. They tend to be pricier than Proto though and both are deep and mid broached, respectively, unlike your Williams, SK, or Snappys.
I highly recommend Ko-ken’s regular line sockets, specifically metric. I have full metric sets for the house. The fit is superb on the nuts and the drive square. I personally dig the half-polished, half-satin look. They are very affordable for what you get. It takes awhile to get them though.
Honorable mention is Wera sockets. They are laser engraved which *****, Taiwan COO (though sometimes they say the COO is Czech but I don’t know if that is legit), and a bit bigger and thicker. But they are satin, have fantastic knurling for your hands, and they fit fasteners great. The size selection isn’t as large as the other three but I’ve been using them at work and have been really pleased thus far. And I’ve grown to be a fan of their color markings.
