Runs ... but not well. It may be different now but I knew an engineer on the Office for Mac team some years back and it did not sound like a pretty port. I have both a Mac and a Windows machine at work and Excel on the latter is lightning fast compared to the former.

Haven't had issues with Word on the Mac. Seems very fast on my MBP. However I prefer using Pages, Keynote etc. if I can help it. I don't use Numbers, as I usually prefer Google Sheets for that.
