Best free substitute for MS Office
I bought a laptop six months ago and it came with free 6 months free MS 365 subscription and it's over now. What would be the best substitute for it. I only want to use MS Word and Excel, cloud storage isn't necessary. I know there is an option of MS Office website. But I want an app and it would be very convenient if it will come with same shortcuts as MS Office apps as I have invested a lot of efforts in it.
LibreOffice
LibreOffice for Windows, Mac and Linux, or Collabora Office for the above and also Android, Chromebooks, iPhones and iPads.
