Nope, it's not.
Come back when it has things like Outline View, first requested oooh about 13yrs ago ( https://bz.apache.org/ooo/show... ), been highest voted or second highest bug/request ever since, but not fixed in 13yrs (apparently it required some reworking of the architecture, and apparently this was done back in 2010...). Having a equivalent of Normal View is also highly voted - I don't use that as much but I can see that if you work on certain types of document layouts it would be essential.
Track changes also lags MS Office significantly.
Excel removed ridiculously low row/column limits almost a decade ago, LO will still only do 1024 columns AFAIK - again, apparently fixing this is too hard. I might only need that for a handful of spreadsheets, but if I have to buy Office anyway for those cases, why would I also use LO and have to master two different tools when I can use Office for everything.
Trouble with OO/LO is similar to electric cars, 80/20 or 90/10 is not a success (against an incumbent tech), it's a problem - if OO/LO can do 90% of my documents or even 95%, I still need Office for the other ones. Similarly if range & charging have improved so that the electric car can do 90% of my journeys or even 95%, that's great - but I still need a fossil fuel car for the others. If I have to have two cars, or two Office suites, instead of one then the new one needs to offer something really compelling that the incumbent doesn't have - and OO/LO doesn't, for me, yet.
