For laptop: controller or keyboard/mouse?

[Estellios]

If you typically play console games you will probably feel more at home using a controller. The gamepad UI is really well done and you can do a lot with it, but if you are used to mouse + kb it will likely have a learning curve to it. I personally use the gamepad as I grew up on console games and am used to it, not to mention I am horribly inaccurate using a mouse.

Otherwise, you will likely just want to mess around with your UI a bit if you are hurting for more space for skills. You can do a ton of customization with the keyboard/mouse UI that you can't do with the gamepad as you are bound to using the crossbar on it.
