You sound like an Illustrator guy to me…
The tablets are great and you can get going with them pretty quickly.
If you REALLY REALLY want to get good at digital illustration, you will need to do what most of us avoid at all cost, and learn the PEN TOOL like the back of your hand. It is frustrating at first and different, but maybe if you spend a weekend on learning it, you will start to get somewhere. It is not intuitive, but it’s important for illustrators. Good luck, and post some work for us to see when you get started!
