Unfortunately in this case, the UI/UX of LibreOffice not even comes close to MS Office's one.
Some FOSS products are that great, but if you come from MS Office, LibreOffice feels a lot like an early 2000's downgrade.
The compatibility and robustness of LibreOffice is excellent, but the UI/UX and something as simple as the default design templates that come with it, it's just not up to the level of MS Office, and customers do judge by that criteria.
I wish LibreOffice was up that standard, so there would be more consumer choice. I even tried LibreOffice as my daily driver for sometime, and I just couldn't stand it.
