iPhone and iPad owners have an amazing problem — iOS is the only platform with all major office suites. The good news is: we get to choose between Apple iWork (Pages, Numbers, and Keynote), Microsoft Office (Word, Excel, and PowerPoint), and Google Docs (Docs, Sheets, and Slides). The bad news is: we have to choose between Apple iWork, Microsoft Office, and Google Docs. And it can be a tough choice! iWork is great for consumers. Microsoft Office is the enterprise standard. Google Docs is increasingly everywhere. So, which one is best? We put them to the test so you can find out!

Word processing: Pages vs Word vs Docs One of the most common things we do with an Office suite is create documents or PDFs. Whether you need to update your resume, complete an assignment for school, or create a flyer for an event, or something else, you need to be able to get the text in efficiently and format it effectively.

Everything from reports to resumes to outlines to fliers and more. Google Docs doesn't offer templates and simply launched you right into a blank text document. So if you're looking for templates, you're going to want to use either Pages or Word.

When it comes to feature set and editing tools, Pages uses interactive formatting in order to let you select different elements. Editing tools and the format menu will change depending on what you have selected. When you're typing, a formatting bar will appear over the keyboard so you can easily adjust fonts, alignment, breaks, and more. You can also add tables, charts, graphs, shapes, and photos in just a few taps. Overall, Pages offers a robust feature set that remains easy to use and works great on a touch interface. When it comes time to export your documents, Pages supports .doc and .docx as well. Pair Pages with a Bluetooth keyboard and it's almost comparable to the desktop version of Pages.

Microsoft Word has been completely designed around a touch screen interface, but will be familiar to desktop Office users as well. (This is true across all the Microsoft apps.) There are tabs for creating, formatting, and editing your documents. In just two taps you can insert or format pretty much any object you'd like. Some features such as tracking and reviewing changes, section breaks, and a few others will require an Office 365 Premium subscription. Either way, the free version of Word offers enough features that a good majority of folks will be able to accomplish what they need with zero issues. One thing I do wish Word had was the formatting toolbar similar to what Pages offers.

Google Docs is simpler than either Pages and Word, and the editing tools more basic. Like Word, I do wish Google had placed a formatting bar directly over the keyboard instead of at the top of the screen. Image insertion is also missing, which will be a deal breaker for many. (You can go back to the web version to do it, but that's a terrible work around.) When it comes to word processing, Pages and Word are equal in terms of feature set. However, certain features such as review tracking, section breaks, and more are free with Pages but require premium subscription with Microsoft Word. So unless you need Word or simply prefer the layout, Pages currently offers the best value for most people. Spreadsheets: Numbers vs Excel vs Sheets

Numbers proves that doing calculations doesn't have to be painful on an iPad or iPhone. Just plot your data and then choose what kind of table, graph, or chart you'd like to use to represent it. The keyboard also changes dynamically in order suit what you're doing. So if you type an = sign in order to start a formula, Numbers automatically gives you a full number pad and relevant buttons you may want to use. There are also lots of templates to choose from in Numbers including ones to create budgets, calculate net worth, track grades (great for teachers), plan travel, and much more.

There's no disputing that Microsoft Excel has been the king of spreadsheets. The main reason for that is the robust feature set. There's no denying in networked office environments, Excel can't be beat. Microsoft did good job bringing the experience to the iPhone and iPad as well. When using formulas in Excel, the formatting bar automatically brings up suggestions to make handling complex formulas an easier job. The keyboard also is suited for entering numbers and editing formulas, a feature I wish the Word application received as well in terms of a formatting bar. Some features, however, will require a premium subscription.

Google Sheets is a barebones spreadsheet application that allows you to create spreadsheets but without the help of a lot of formatting tools and templates that are offered in competitor apps such as Excel and Numbers. However, if your main purpose is to track data between large groups of people, Google's collaboration tools are some of the best around. Just share sheets with whoever you need to via email and once they accept you can view changes, make comments to each other, and even see who's changing what in real time. If feature set and advanced tools are your main concern, there's none better than Excel. If you're new to spreadsheets and would appreciate a balance between ease of use and feature set, Numbers is for you. If collaboration tools are what you're after and your feature requirements are minimal, Google Sheets will suit you just fine. Presentations: Keynote vs PowerPoint vs Slides

Keynote has always been Apple's best office app, and the same holds true on iOS. Aside from offering gorgeous templates to choose from, Keynote's interface feels as it if were made for the touch screen. Adding slides couldn't be easier, and neither could tweaking them to your liking. Just like the other iWork apps, formatting and editing is interactive, so the menus will change depending on what type of content you're working with. The Keynote Remote feature also lets you use one iOS device as a remote to control a presentation on another, or even on a Mac.
