Ask HN: Microsoft Word on Mac is frustrating. Any suggestions?

I've always kept it up-to-date, but it is very slow (slower than my keystrokes!), shortcuts don't work and change on their own, it crashes in the middle of typing a document, the more words I type, the slower it gets...

I'm genuinely frustrated with Word on Mac, but don't want to switch to Windows at all. Any suggestions on how to fix these issue? Is there any alternative available?

Thanks in advance.
