XKings are pretty fast, relatively low grip tyres- not XC racey really but not far off it. So you probably don’t need a grip monster, just something grippier.
Hans Dampfs can **** off, if you want a fast wearing, mud-cloggy, draggy, not especially grippy tyre then they’re bang on though.
Butcher has a DH version but the control and grid versions are trailbike tyres- pretty common for the same tyre to come in different versions, like the minion etc. I don’t like it on the front personally, I think the rubber’s a bit too hard but it’d be a lot more grip than you’re used to- the tread pattern is ace. And it’s reasonably quick rolling. Could do the job well but I’d still go Minion 3C instead- very similiar, better rubber.
Not sure what Purgatories are for tbh, they’re about 4/5ths as draggy as a Butcher and a lot less grippy. It’s not a terrible tyre, by any means
