Tbh, I draww mostly on my phone because:
1. It's easier, you can always edit it when you screw up.
2. You can use any color you want.
3. Traditionally you can't edit it whenever you want but digitally you can add effects that normally would take ages and would cost a lot of effort to pull of.
4. Infinite possibilities with different brushes and other things, like for example in ibis Paint X, you can do things that on paper you normally couldn't.
