Cam, for me all the tough-hard bits Wera offers wear out in a pretty much identical fashion whether it’s the C or E 6.3 type. Phillips and Pozi drive are obviously the worst offenders among them. And it depends a lot on the fit inside the head of the screw. I’ve had bits look battered after only a couple of screws without any of the obvious reasons like cam out. Wera really doesn’t have any magic sauce here with their tough-hard type bits. I rarely use them these days to be honest, for the most part exactly because of experience like this.
Also it’s really hard to tell, with all the changes Wera made over the years, what type exactly was/is in each set.
My stuff, except for one Advent-Calendar set and a couple of singles (especially stainless), is so old it’s even hard to find a more recent successor. I don’t even know if they still make the distinction between “tough-hard” and “hard”.
And then there were the gold colored ones with “diamonds” sprinkled over them and the black “Impaktor” ones also with “diamonds” sprinkled on. At some point they made changes to both of these types as well. But those were ultimately the ones that offered the most wear resistance/ lasted longest for me. And I still have & use some of these with different kits.
I’ve honestly lost oversight on their current offerings. It‘s been ages since they shipped me a paper catalog which was like the “Bible of available bits” at a time. Explanations of the different types/series included.
All I can really suggest is, if you feel like they are not holding up to your expectations, get in contact with Wera and tell them just that and hopefully they ship you some replacements and advise on what to buy from their line-up with future purchases.
Last but not least, consider if you might get more out of/ better results with another brand’s bits.
My personal experience is that Wera’s quality has not really improved over the years, it’s hovering around mediocre/acceptable for most stuff and they are putting their efforts more behind the “tool rebel” branding/ marketing instead of the quality of the products they offer.
In a line, excessive wear on “tough-hard” bits from Wera is not unknown to me.
Here’s a prime example from a set that I keep around solely for the purpose of “dirty demolition”.
Kind regards,

But still I'm not detoured, I'll buy another wera set if I need too.
