I’ve seen this question posted a few times. My go to are the Centrofix line from Wiha because they hold the longer anvil of the Japanese bits like glue. Virtually no flex. Obviously not Japanese made but if you’re going to invest in Vessel/Anex/Sunflag etc. bits, this is the way to go. They also work with the shorter C6 bits, standard bits, double sided, and dual anvil bits, so very versatile too. In the picture below you can see the anvils it works with.
Additionally, I keep a Centrofix bit adapter in my Felo Smart Handle so that I also have a T Handle available. The Hazet 810BH works with the longer Japanese anvil as well, just not as secure as the Centrofix. Hope this helps.
