Recently, Google released a revamped version of Quickoffice for free to the Play Store. Now, the company has two office suites with nearly identical interfaces. Which one should you use? Productivity blog Make Tech Easier attempted to answer that question.
The site compared the two services and found them to be comparable for the casual user, but if you're going to do any real work, Quickoffice is probably the way to go:
As far as being a competent document editor goes, Quickoffice is still the superior app. Google Drive is no slouch, but Quickoffice simply offers more features. If you have to create a document on the go that contains tables, images, colours, and charts, you will have better luck using Quickoffice to crank it out. Not only is the interface easier to handle, but since the editing takes place offline, it's going to provide a smoother experience.
It's also worth pointing out that if you want to do any work with Microsoft file formats, you pretty much have to use Quickoffice, or convert them later. Fortunately, Google recently updated both apps so that if you open a Google Drive file in Quickoffice, it will bump you over to the Drive app (and vice versa).
