@Steffie Ha, another change of heart by me! To my surprise & amusement, from early this month i've found myself [willingly] looped back right to the beginning re an Office suite in Linux, to where i was when i first experimented with Linux in 2013 [back then i was still a Windows user]... ie, now once more i am using Libre Office, but this time around as my default, & for the most part rather liking it. This could not be a more extreme reversal of opinion by me if i tried! 
Whilst in many ways my previously posted usage of MS Office 2010 Pro in a WinePrefix had continued to work well overall, i chose to revisit LO once more [& subsequently adopted it] early May coz:
There were various reasons of principle, as well as pragmatism, that drove me from Win to Linux in 2013/14, & my recent adoption of MS Office in Linux had been weighing on my conscience as implying i was still beholden to a company i dislike. It's been making me feel "dirty".
For security reasons i strongly prefer to run most of my installed Linux pgms sandboxed with FireJail, & that especially included MS Office given that it & Wine itself are widely regarded as potentially compromising a Linux user's security. However, to my disappointment i discovered that whilst running any individual MS Office pgm in FJ still worked fine, whenever i would launch any subsequent one [& after all, i commonly need Word & Excel simultaneously] they would both lock up, either instantly, or sometimes a bit later, needing both to be killed, with data loss. Running them naked [no FJ] worked well, but it just always felt "wrong" to me.
I rediscovered that LO v5.3.x, available via their PPA, has their MUFFIN "Ribbon" -- i much prefer ribbons over the older UI. Furthermore, compared to my earlier unhappy experiences with LO, i found that with v5.3.3.2:
a. Much better compatibility with most of my existing .docx, .xlsx & .pptx files that i retested [as long as i do not need to subsequently (in LO) need to edit them... for new docs, or when editing old ones is needed, see #f].
.
b. I learned how to customise the right-click context menu to give me most [albeit not all] of the functions i rely on from MS Office 2010.
.
c. I learned how to customise the Toolbar also to my tastes.
.
d. I serendipitously discovered several pretty cool features & functions i'd not realised, as i did #b & #c.
.
e. v5.3.x has done something nice with its font management & display. Earlier times that i tested LO Writer, my docs rendered "ugly", but now somehow with this new version they are "nice". Hmmm, i just realised; credit for that improvement might rest with LO, or possibly instead with my distro -- Mint 17.x KDE4 when i first tested LO in 2013/14, but [the more sophisticated??] Maui Plasma5 nowadays.
.
f. Whilst the LO .docx, .xlsx & .pptx files compatibility is notionally good, in practice i found it to be dangerously untrustworthy, frequently damaging some of my docs [either LO-edited MSOffice-originated ones, or LO-originated ones in MSOffice2010 file-type] when later reopened. In contrast, the LO default ODF file format [which gave me hideously bad incompatibility pains when first tried in 2013/14] now seems to be quite excellent for my docs. Weird how some things can totally turn-around!
.
g. Whilst the method seems arcane even labyrinthine, i learned how to customise Writer's & Calc's Default templates to match my needs.
.
h. Again the method is unnecessarily indirect, but i worked out how to edit Calc's Comments' format, balloon size & position.
.
i. I discovered Calc's cell Validation with Pick Lists, important for me in Excel, & which initially i thought was missing in LO.
.
j. Being a native Linux pgm suite, LO completely unlike MS Office in WinePrefix, & also actually better than WPS Office for Linux, really excellently integrates with all my Plasma5 colour schemes, themes, & KWin Desktop Effects. Cool!!
Whilst overall this new LO version has proven surprisingly pleasant & powerful for me [hence it's now my default], it's not all ponies & rose-petals:
Its current MUFFIN ribbon is not user-editable
Calc seems not to have cell/column filtering based on cell colour [bummer]
I have not yet deduced how to make my MS Office macros work in LO.
Not the end of the world, but disappointing, is the inability to pin specific "Recent" docs to the Recent menu, for those files i need to frequently open [MS Office 2010 & WPS Office both do this well].
All in all, this latest LO has made me almost entirely have to rescind my original negativity about LO. I am happy to be now proven wrong [or at least, that my earlier views have been rendered obsolete]. Yay.
