Among those two options: Wera Kraftform plus. Why? My main supplier stocks the Wera Kraftform plus series and because of sale volume prices them very competitively. Generally, I have no bad things to say about them, they work, they wear, they get replaced by me when necessary.
The Witte I would have to special order, or buy from another vendor. None of my frequently used (industrial) suppliers sell Witte outright (or, to the best of my knowledge, use Witte as manufacturer for their branded/private label stuff.)
And then, if I did go the extra mile of a ‘special order’, which I sometimes do when not time sensitive, I would always get the PB Swiss demolition drivers because I ultimately like them best. But that was not the question.
Kind regards,
Olli
