There are several top notch independent versions of Microsoft Office that run on Android tablets, but none support Word's review markups and comments. The solution is to use Word running on your PC back home, and displayed on your Android tablet where ever you have a connection to the Internet.
In my case, I use TeamViewer. It lets me see and interact with the screens of other computers, whether my own desktop or that of relatives who need tech support.
TeamViewer is free for non-commerical use. (The business version costs $689.) There are other similar products on the market, and certain editions of Windows include the capability as well. But I found Microsoft's implementation too painful to use.
To make access painless, you create an account with TeamViewer, and then on each computer or table you use, you set up the same account. This lets you access any of them with just a click on the computer's name.
I use very high resolution monitors at home, but a typical tablet has a resolution of only 1280 or 1024. TeamViewer changes the resolution of the remote computer to match your local one, should the local one have a lower resolution.
My desktop back home has two (sometimes three) monitors. I really appreciated a recent update to TeamViewer where I can now choose which monitor to view, rather than seeing all three scrunched across 1280 pixels..
