It really depends on what you’re looking to use it for. For example, digital artists tend to prefer tablets since they’re easier to draw on with a stylus. Tablets are also great for photo editing and streaming movies if you get one with a large enough screen size.
However, if you want to do things like create spreadsheets, type in a word processing program, or do intensive 3D animation or modeling, you’re better off with a laptop than a tablet.
