I was going to start a thread on some of these, but I think adding to this one is better. I make no claims that the below are the best, or that they have been scientifically tested, but I do have some of my opinions and observations on them. This is some of my hex "stuff":
Looking at the pics:
Makita: very old, has flip out handle for leverage. I never really warmed to this one, as the large tip gets in the way a lot.
Craftsman: Also old, USA, and not a favorite. Works ok but nothing great about it either.
Klein: The Klein is actually an 8:1. Each bit has two ends, the bits are in a sleeve that holds two bits, and the tool holds two sleeves. It's really fast and easy to change bits. If you only have one screwdriver, this is the one to get. In particular I think it'd be great where space is very limited, like in a motorcycle tool kit or a 911 frunk. Because the bits are double ended they are not as standard as single ended, so they are harder to find.
Whia: insulated and nice in the hand. The bit storage is just ok as I am not a fan of the rotary selector approach. The end also is a bit of a pain to get off sometimes. Still if you need insulated, this is a nice tool. Evidently it's not available any more, so I am lucky I got mine from Zoro about 9 months ago. If you're OCD the bits do rattle in the hard plastic handle which may or may not bother you. It's a quality tool, but I only reach for it when I need insulated.
DeWalt: This was an impulse buy at Lowes, and it is also a ratchet. The bit storage is very dense and the tool can hold a lot of bits. However the bits don't always store that well and it can be a pain to get a bit in or out of storage. Also the ratchet is just ok - it seems coarse and gritty.
Williams: This is my preferred guy for the shop. It it also a ratchet, but unlike the DeWalt it feels very good in use. For those that don't like ratchets, just use the middle locked setting.

USA CoO, and it is just a pleasure to use.
Vim: This little guy is very new and I have not used him seriously yet. I got him as complement to my Chapman set (not shown). It's very small, and it also has a reversible ratchet on one end. When you need something like this you really need it...
The last is a Wera set. I got this as a treat for myself.

It's also very new and not used much yet, but it looks really nice. I got it mostly for the two drivers. However, it would also be a nice compact option for under a motorcycle seat or in a frunk.

PS. The Wera, Vim, and Williams are all the fault of other posters on GJ. Hopefully I can help some of you spend your money as well.
