Which (in your opinion) is better and why?
Vengeful quills or virulent quills?

This question has been asked many times. Try a Google search like sprite ultimate site:forums.spiralknights.com or vengeful virulent site:forums.spiralknights.com. Good luck.
Many of those questions were posted before the abilities got patched. According to the posts I read, there were apparently some bugs and nerfs. Considering that, the information on those older posts is unreliable. I've read pretty much all of those posts, yet still haven't come to a conclusive decision.

Most of those posts occurred after patches and bugfixes (which was in August I think). But I agree that it can be hard to tell which information is reliable. Try looking at recent threads, such as this, this, and this. (The last is from five days ago. That's what I mean by "asked many times". :)
By the way, I'd be giving you actual information if I had it. But I've never used Virulent. Cheers.

I would go with Virulent Quills because Vengeful Quills can spread to undesired targets like gun puppies that you didn't mean to wake up.

I've always preferred Vengeful to Virulent, but it's purely opinion. Both add insane damage, however Vengeful adds more damage in a a very broad area, whereas Virulent adds slightly more damage than Vengeful, but in a condensed area.
"I would go with Virulent Quills because Vengeful Quills can spread to undesired targets like gun puppies that you didn't mean to wake up."
This is a bad argument, unless you can give a reasonable and common situation as to when this would actually have any effect. Any place where you don't want an undesired spread is a place where you shouldn't be using your quills at all, whether it's Virulet or Vengeful. And I say common because choosing one quill over another for something that rarely happens is dumb considering how hard it is to get them in the first place for the average player.
Because the way i see it virulent has more damage potential on single targets compared to vengeful (virulent's explosions deal stronger poisons than vengeful) but can also spread to other targets.
