I use FireAlpaca for my skeletons usually, simply because my decrepit computer opens it faster than my other programs, and it's what I learned on so it's easy for me to do quick and fast lines; appropriate for page skeletons I think. Nothing more than just a transparent layer and such here!
For my actual lineart, I cannot go without Clip Studio Paint. I love love love it for comic work, even though I don't even think I'm using it to it's fullest potential.
Clip Studio also takes up coloring duty when I need it to! Pretty much everything I do revolves around these two programs; I don't draw that much physically these days due to convenience and lack of practice.
(i also use too many tabs shhhhh don't mention it
But yeah! That's about everything! Here's a shameless plug!
