So I wrote this late at night and with broken AC in the Arizona heat and as a result it was more glib and dismissive than I would intend. Not a very useful post, even if some do agree with it.
Although we're an all Apple household (2 rMBPs, 2 iPad Pros, 2 iPhone 7's, 2 Watches, 3 Apple TVs) I'm very much an advocate of Microsoft Office 365 for the simple reason that is excellent software and, in my opinion, excellent value for money. A terabyte of storage each, the core suite on all our devices for $11 per month is just a plain good deal. In my opinion Office is one of the best (collection of) Apps on iOS period and the Mac version is no slouch these days either (though I'm not an Excel power user and I hear that's not quite up to snuff on the Windows versions on large sheets). It's true the web and mobile SKUs have some arbitrary limitations - it doesn't seem to be anything inherent to an iPad for instance that shouldn't allow you to be able to create a simple TOC. That is a little frustrating and I work around it by a) having template documents with the features I need and b) Not creating many documents on iOS in the first place, just using it for mobile review and editing. I wouldn't recommend for most people as the sole place to author but clearly, as we see above, it does work for some.
As for it's stability, and that of OneDrive, I've never had a single problem reading or writing both Personal and Corporate OneDrive, iCloud, or another cloud storage solution owned by the company I work for that I won't mention here. We have a space on our internal Jive specifically for Apple users in the company and, of all the challenges people might face using Apple kit in a Windows oriented company, using Office is never one of them.
I don't particularly place much stock on an unsourced "I heard on Reddit it's bad". In fact I thought it was a rule on this forum to cite your sources when you say such things.
