In my quest for a decent set of ball drivers, I purchased the SAE and metric sets of the Bondhus ProHold drivers from RTL Fasteners.

My first impressions are very favourable. The ProHold button does a great job of holding onto socket head screws, but doesn't interfere with rotation. Only time will tell how well they do in the long term, but I have high hopes. And they have a new home in the workshop.
