      I have been using LibreOffice for many years and it does exactly what I expect it to do.

      It covers nearly all functionality of MSOff, is frequently updated, is extensively compatible. There is one omission: it lacks e-mail client, but it's on purpose, and you can always install Thunderbird :)

      it's ugly, the buttons are in the wrong places (and i still love wordperfect!!) clunky, not truly compatible with industry standard MS office. selection is awkward, the UI is not userfrienldy. and the support staff are not interested in fixing it. the 'themes' rely on firefox extension and haven't worked in the last two versions. i went back to windows just for office.

      Apache OpenOffice vs Microsoft Office Suite
      pros, cons and recent comments
      Free, no ads like many other "free" programs, and open source.
      Positive comment over 3 years ago

      dansker13 Apache Open Office is based on the old StarOffice, which 10-15 years ago was way ahead of MS Office - and so is AOO to-day. The other alternative is LibreOffice, which is also based upon the same old platform. Those two are especially efficient for work, but also fill any need a private user can have

      It has all that MSO has and is more user friendly, faster and free!

      124MB download, no invasive services, doesn't spike CPU or HDD I/O, less cluttered GUI, seems to be compatible and efficient. What's not to love?

      Runs on Linux, open source, nice and easy-to-use interface
      Top positive comment  over 1 year ago

      forgionealberico Clean modern interface, more compatible with MSOffice than Libre or Open, but heavier to run on slow hardware probably

      Between OnlyOffice, FreeOffice, WPS and LibreOffice, the closest i could get to a Microsoft Word document was with OnlyOffice and since i need the best compatibility possible, i liked OnlyOffice.

      jilv220 Great compatibility and similar layout to MS office suite.
