Alright, let me try to just get this all in a nice list here.

For sketching I usually use procreate with these brushes:
Most of the standard pencil brushes, usually 6b or Hb pencil
Monomania by Truegrit (https://www.truegrittexturesupply.com/products/monomania)
Kolormarc markers also by Truegrit(https://www.truegrittexturesupply.com/products/kolormarc-markers-for-procreate-photoshop-affinity-clipstudio)

Then I usually use Clip Studio Paint for finished illustrations:
The main brush I use is this one here, it's my favorite, the Caspar brush (https://assets.clip-studio.com/en-us/detail?id=1708763)
Then I also use this Rough Yeti Brush for texture and crosshatching from this pack here (https://www.zombieyeti.com/free-manga-studio-5-ink-brush-pens/)
AAAAAND I use this Turbo Textures Brush Kit from Retrosupply for that nice analog textures (https://www.retrosupply.co/products/turbo-textures)

Hope that helps!
