Microsoft Office 2016 for Mac is awesome! It is actually currently available and has also been freely downloadable in a preview edition for about the last six months or so. Note that it requires OSX 10.10 now, unlike previous versions which were more flexible.

However, I believe (would obviously need to verify the published specifications) that it's pretty much at feature parity with Ofice for Windows. I'm not sure about scripting features, and some of the more esoteric stuff, but I use Excel, Powerpoint and Word regularly, and it's great to have the same familiar look and feel across platforms. Certainly better than the previous edition for OSX and I expect that's what you were thinking of; it was Office 2011 before.
