I have used SoftMaker Office on Windows and Linux for the past 10 years. I have had great luck with importing files in Word or Excel formats. I also love the fact that you can still have the traditional toolbar or classic menus style which I find more productive. There is also a tabbed interface you can use if you desire. The price of their products is reasonable and the the tech support is good. You are also not tied to the monthly or yearly subscription model like Microsoft Office is pushing. A good office suite.
The disadvantages are that there is no cloud version. I also do not like the auto-hyphenation. This can be shut off though. Not a bad Office suite and one I am happy to use daily.
