While there is an essential "sameness" to all these apps, you will still find that some features found in the Windows version are nowhere to be found on the Mac. For example, the option to add a pop-up calendar to a table--a feature you'll find in the Windows version--isn't available on the Mac. But...if you use your Mac to add a properly formatted date to a document with a table including that feature, the field will retain the calendar option when you open it again on a PC.
This raises an important point: Word for Mac is top-notch when it comes to collaborative work. This is obvious when it comes to basic document editing. Email a document to someone, have them make changes, and send it back to you. If they're using the current version of Word on the device they edit with, the transition is seamless. But, better yet, share your document using OneDrive, OneDrive for Business, or a Microsoft Sharepoint, and you can have dozens of people working on the same document at the same time, each without interfering with the other's changes. Word's collaborative tools also include threaded comments, so you can see and interact with others within the comments on a document.
Word 2016 isn't without disappointments, but they are by no means deal killers. Word takes no advantage of Apple's Autosave and Versions features. So you're stuck with what now seems like a vestige of some ancient past. Have a power failure? Dog step on your power strip? You're relegated to the weeping and gnashing of teeth you no longer expect when bad things happen and you have unsaved changes in a document. This also seems to be tied to Word's collaboration features, which, while excellent, are not as dynamic as I'd like them to be. If you're editing a document while someone else is also making changes, you don't see their changes until both they and you save the document. (Compare this with Pages, which updates changes almost as soon as they're made, no matter who is editing the document.) Finally, Word doesn't support Yosemite's option to rename and/or move a document using the menu in the document's title bar.
Microsoft Word 2016 is an excellent update to what is, for most users, an important business tool. Changes to the program's user interface make it easy for anyone to bounce from Word on a Mac to Word on any other platform with a minimal transitional curve. Word's collaboration features make it possible for business users to work on the computing platform of their choosing without making significant sacrifices.
While the program doesn't support some of Yosemite's more important, user friendly, and bacon-saving features--such as Autosave--the overall user experience is superb. In short, Microsoft Word gets the job done without getting in the way, If Word is your primary tool for getting work done with words, run, don't walk to upgrade to Word 2016.
