I have both plus a large smart phone. It really depends on what you want to do with the item. For ease of use and quick access, your phone or tablet is the way to go. However, because of their design, they aren't the best for working on business tasks editing. I know some will argue that with all the apps available you can do everything with a tablet.....and for the most part it is true... however, there are more refined details you'll only be able to do with a laptop. The newer laptops can double as a tablet as well. Some are detachable so you have the option of how to carry it. The biggest selling point for a laptop is the higher capacity of work which can be done. But again, depending on how much you spend on your tablet, you may have those options too.
Personally, I love the accessibility of tablets for quick things. But, when I'm going to sit and work on something, I prefer a laptop. I feel more productive on a laptop.
