Ranked in these QuestionsQuestion Ranking
Pro Syncs between devices
By logging into Chrome using a Google account it's possible to sync history, extensions, passwords, bookmarks and other settings between devices. This makes it great for anyone working with multiple devices as it allows experiencing consistent context when in the browser.
Pro Excellent HTML 5 feature support
As of February 2015, Chrome scores highest of all browsers for HTML5 compatibility.
Pro Good performance
Pro Installs extensions without requiring a restart
Pro Automatically updates
Chrome updates in the background ensuring you're always on the latest version. This makes it much more likely that sites will work on your browser, since (almost) all Chrome users will be running exactly the same version.
Pro Great built-in developer tools
Chrome comes with built-in developer tools, making testing and enhancing web pages simpler for those of us involved in working with such technologies. As well as being beneficial to developers, this also has some benefit to non-technical users; in that by making testing simpler for developers those developers are more likely to use Chrome for their tests, and can spend more time making improvements over investigating underlying causes of issues.
Available as a free download.
Pro Backed and supported by Google
Whilst Chrome is based on the open source browser Chromium), Google reviews this code and build on top of it. This means it takes (and contributes to) a number of the benefits of the open source model whilst having the resources, support and investment of a major company.
Pro Plenty of extensions
Pro Simple user interface
For example, the address bar is also the search bar. Google calls it Omnibox.
As of March 2015, Chrome is the most popular browser on the internet, with a 43.9% - 63.7% market share, meaning most developers will be testing their sites against this browser to ensure compatibility.
Con Huge memory hog
Each tab and extension in the browser uses significant chunks of RAM, giving the browser poor performance on machines without enough RAM to supply.
Con Gives too much weight to Google on the future of the Web
Con Online tracking by default
Chrome allows opting out of tracking by going to settings > advanced > privacy and un-checking any unwanted services. Alternatively Chromium can be used to get a similar browser experience without Google's services on top of it.
Con Increasingly slow
When Chrome first came out, it was known for being lightweight and very speedy. Over the years, more and more features have been added to Chrome. Because of this, crashes, errors, and general laggy-ness has increased noticeably.
Con Blurred fonts on Windows
Fonts on Windows are blurred, that is especially noticeable in light fonts on dark background. Small italic text is hard to read.
Con Bad for battery life
Drains battery life on both Windows laptops and Macs much quicker than the alternatives. It can shave hours off the battery life of any non Chromebook laptop.
Google Chrome is proprietary software, meaning that it is not open source.
Con Does not hardware accelerate HTML5 video correctly
Chrome is unable to hardware accelerate HTML5 video correctly which makes playing 4k video on laptops a poor experience filled with lag.
Though there is a workaround for YouTube in that a plugin can be installed to force Flash playback instead of HTML5, which plays smoothly and has no HW acceleration issues.
