Much cheaper.

This pisses me off so much.
First off, you don't get as much tools as you can use, unlike using a digital program like Sai, Photoshop, heck even Gimp or Paint.net. Secondly, If you want to have all of those tools you're going have to go out and buy it yourself, adding up to the cost, You can't even customize your pen size or other options like opacity. Thirdly, If you want your drawing or whatever to be on your computer you're going to need a scanner, which can cost around $100 or more. The only thing that's better than digital art is that you can bring pencil and paper wherever you go, but that's about it.
I'm going to put out a few cons and pros for each thing.
Digital with Tablet
Pros:
Can adjust pen/eraser options freely.
More smooth.
Many tools depending on your software.
Line tool.
Layers
Vectors.
Many editing tools like changing the hue and such.
On computer, so no need for a scanner.
Much more.
Cons:
Not portable.
Can cost a lot of money, depending on what you buy.
Need a tablet to draw good unless you're a mouse wizard
Pen and Paper:
Pros:
Portable
Don't need a tablet to draw well because you have a pen.
Cons:
You need to buy many tools, unlike a digital software comes with all tools.
Need a scanner if you want to put your drawing on the computer.
No editing tools.
No layers.
No vectors.
Anyways, back on topic. I don't have much tablets for OP but Wacom or Bamboo is pretty good on what I heard
