LibreOffice is clunky; it suffers from the "UI designed by a programmer without input from users" syndrome (The GIMP has that problem, too) and its main virtues are that it's free and runs on Inux, Mac, and Windows. LO's word processor is simply not as capable as Pages, or WordPerfect, or MS Word or... well or any other word processor on any platform that I've tried word processors on, going back to DEC All-In-1 on a VAX, though admittedly I was accessing the VAX through a dial-up connection. LO's presentation system isn't as bad, but it's not up to PowerPoint or Keynote. LO's spreadsheet system is better than Numbers (not difficult) but simply is nowhere close to Excel. Sorry, but these are the facts.
Let the downvotes begin.
