As stated above, there are basically 3 different ratchets in 3/8 drive (excluding the quick release). The regular, the long handle flex head, and the fine tooth!
That's about an average selection for a European tool manufacturer, and they are all perfectly good tools! If you are buying a set, as in a set of sockets with a ratchet, Sliding T and a couple of extensions, then I don't think you have much choice as the sets all seem to come with the basic ratchet. I own one and it's a good serviceable tool!
If you were ordering just a set of sockets, then I might consider the long handle flex head as an alternative, but both are fine!
As to the choice of Hazet, it's a good one. Quality wise, they are up there close to Stahlwille, and not far behind Snap On, if at all! Styling wise they are different, but that's what makes the world fun! Sure, Hazet don't have high polished chrome, but they are really tough to use. Unlike the highly polished tools, they don't show wear much!
I think it comes down to where you are. If you are in the U.S. then U.S. made tools are relatively cheaper and probably make more sense! You'll be paying more for the Hazet than for similar quality domestic tools, so that's why some folks don't get it! If you are in the U.K. or Europe then the U.S. stuff is seriously expensive, so tools from makers such as Hazet make much more sense!
Personally, owning a mix of tools, I can say that I love my Snap On ratchets, and in fact most of their stuff, and don't think they can be bettered, but they are not right for everything! With the Hazet, you can jump into a job yanking on rusted fasteners knowing that you won't damage, of even mark, the wrench! My Hazet 3/8 drive rides around in the back of one of my vehicles and I know it won't get damaged rattling around in a box!
P.S. Last time I visited a Porsche facility, all the tools were Stahlwille!
