I have a Wera tools set that has a ball on the long end and straight on the short end. This has always worked well for me. In fact, today, I needed them for removing an UHDW plastic plate on a jig. The short straight end was perfect for starting to undo the screws set with removable LocTite then used the ball end to quickly remove them.
In this case, I could have used the short straight end all the way, but I've definitely had to use the ball end to even get something started. Seems to be the best of both worlds and gives the end-user the choice.
