I've also done a bunch of research into comprehensive hex and torx bit socket sets.
I'm quite confident no tool company has a complete master kit as I'm not quite sure you could fit it all in one blow molded case.
Probably one of the biggest sets I've seen is the BLPTHC87 87pc. Blue Point set. It includes torx, tamperproof torx, long torx and external torx. Also includes hex up to 19mm and 3/4" with long in the smaller sizes. Probably the only box it doesn't tick is the ball hex.

The 80742 84pc. Gearwrench set is another comprehensive set and it includes ball hex in long length. Again not a complete master kit but a good selection of the more commonly used types of bit sockets.

I ultimately chose the sets by Mac. I liked the arrangement in the cases and the availability to add sets as I needed them. The ability to warranty one socket easily w/ my Mac guy has been very convenient a couple times! At one point I had the bigger all hex set that included the smaller 1/4" sizes and the stubby but traded it in a couple years ago for the pictured sets.

Eventually I plan on adding one of their long torx sets and their 1/4" drive hex bit set as pictured.
