OK for a free application but not as good as earlier versions
LibreOffice is a good free substitution for the MS equivalent. Unfortunatelly the ver 5.x release currently shows reduced performance - the applications respond slowly to mouse clicks and inputs from the user although I am using the newest hardware (early 2015 MBP model). This is really irritating.
-The displayed equations are not optimized for the retina display and look like a low-res image.
-I am still not convinced that the revamped interface is an improvement, although I do see some handy new features and ideas there.
-When defining my own colours by specifying RGB or CMYK values, LO resets them to some other values leading to different colour being defined, although indeed the differences are not too significant.
-Recently I had also problems with a Writer document containing a lot of math and page breaks which lead to crashes of LO. The same document on a Windows machine created no problems at all.
Bottom line: nice application but consider sticking with the 4.x line of LO until the bugs in 5.x are removed and the applications are optimized for the new Apple hardware.
