Although it is a big investment to start with I believe digital art is the future for artists because, in the long term, it will reduce your material costs. Its also very accessible, I just need to grab my tablet to draw nowadays which has all the colours and all the pens.
On saying that you cant beat getting your hands dirty, making a mistake with no undo button and trying to get away with. The creative process will always be a balance between the two so my advice is don't take sides, bake your cake and eat it.
Here are some recent digital pieces I've created where I have tried to incorporate my IRL style of brown paper, Posca pens and stickers.
