Pros
Pro No need for a separate tool
Chrome comes with DevTools baked in. So if Chrome is used for development and it fills the need, there's no need for a separate tool.
Pro Extensible
Custom drivers for e.g. API testing or static HTML testing exist and are easily built. Driver modules allow you to extend the main driver (e.g. Selenium or Appium) with ease.
Pro Platform agnostic because it is configuration driven
For test suites crossing multiple platforms, selecting the test target platform can be driven entirely by configuration.
Pro Seamlessly automate mobile and desktop browsers
Based on either Appium or Selenium, the API remains largely the same when switching between different platforms.
Cons
Con Limited to the box model of elements
DevTools only displays measurements of the HTML element's box that means that it can't measure, for example, relative to text's baseline or objects within a canvas element.
Con Does not measure distance between elements
DevTools measure dimensions of HTML elements only.
