Funny, I just replied in the Chinese Grom thread about this.
Another vote for Vessel crosshead drivers. Best I've ever used. I have both of those impact drivers you just ordered.
From my research, JIS has merged with DIN to reduce confusion since they were almost exactly the same anyway. Phillips is the same as it has always been. If you only work on Japanese or European bikes & cars, throw out your Craftsman and Snap-On Phillips drivers, they just don't fit the screw heads.
Vessel has adopted the new, more universal standard, at least for advertising purposes. I have some of the older JIS and some newer but I haven't used the newer ones enough to be able to tell if there's any difference.
Here's how well a Vessel tip fits. Yes, that is a 150mm #2 being supported in a hose clamp screw by the tip only!
