That looks like a rather interesting set of sockets! The problem is they are CAD $130 on our Amazon, which puts them at roughly the price of the Matco's. It's tragic what some stuff that is reasonable south of the border costs in Canada... How well do they sit on fasteners? I don't mean the magnetic draw, but if they slip when they see some torque... Recently long handle 1/4 ratchets have become my new favourite tool and are replacing a lot of the lighter stuff the 3/8 saw. The reason I am thinking truck brand is getting a warranty on stuff like Gearwrench and Carlyle involves a cross-border drive or a multi-week wait - not something I want to risk with my primary set.
