Gang,
I'm generally not a fan of modern Stanley tools, but I do like the 100 Plus drivers, and most of the drivers I've got are 20 - 30 years old. They have comfortable handles, strong shanks, and bitch hard tips. And, the larger size drivers have a hex bolster on the top of the shank, a feature that comes in handy on old frozen rusty screws.
I like to think these 100 Plus drivers are so good that even Stanley couldn't screw them up or abandon them. If you'll recall, Stanley has taken down a lot of great tool companies over the decades.
So, Hickory, I think you made a good choice in your new 100 Plus drivers. The more you use them, the more you will come to appreciate them.
