That depends on what you're doing. There's no "best" chip, just like there's no best car, best house, or best pair of shoes. It all depends on what you want to spend and what you need your processro to do.

Here at Silicon Insider, we track more than 100 different kinds of microprocessor and microcontroller chips, so we're always on top of the business. We can help you (or your clients or customers) decide what chip's best for them.
