In case anybody else goes through this thread looking for options, here are some pictures of my megadora 930 set. I really like them so far and have had them a few months now. I probably didn't need the whole set with the flatheads but the tray is nice to have and I like tools, lol.
I wouldn't go crazy hammering on them as chisels (there is a dedicated megadora chisel) but the through tang design is really nice to have for cross heads that have started to strip or stuff that has been painted over. If I do need to wack them, I can just do that with confidence and not worry about marring or breaking the handle. It also gives a nice weight to them in your hand.
The hex bolsters are in JIS standard 8/10/12mm depending upon the handle size which is nice if you are working with other metric tools (vs keeping an imperial wrench around for American drivers). The bolsters are part of the shaft and have a nice angled ramp up/transition that helps easily guide box end wrenches on. There is a also a sort of washer lip at the base which helps hold a wrench in place and protect the plastic handle; well thought out. Compared to a full length hex or square shank design, the bolster keeps the shaft narrow for fitting into small spaces.
The stubbies in the set are just the standard megadora 910 style which is fine because you probably wouldn't be hitting a stubby anyway. I love the grips on them, the shape fits your hand well and the material feels really nice. I have used the flathead stubby a bit for carb adjustments and swapping jet holders.
These are the "jaws-fit" heads with serrations on the crossheads and while they do seem to fit well, I can't say that I have another set of JIS drivers to compare to.
The only thing that I don't particularly like is that Vessel uses a P2x150mm in the set and the length can be a little awkward for general use. I figure I'll probably order a P2x100mm eventually.
As for the other lines, the wood compo drivers definitely intrigue me and I'll probably find an excuse to try one eventually. The 4500 series look cool as well if you wanted a smaller set vs the megadora 930. The ball type also look excellent for smaller low torque applications like computer stuff, I used Wiha precision drivers with the rotating caps when I did that professionally.
