I used to think so. But over the past 5-10 years I’ve seen the quality of the mac application go down. Things, that used to work, are buggy. Bulleted lists, indents, even scrolling. Compatibility is going, too. I add pictures to find them not rendering once the file has been opened on a pc. I get files back from the customer with figure references having turned static. I’ve been using Word in some way or another since the beginning and it has never been that bad. Eventually this trend will degrade the usability to the extent a competitor would emerge.
