The features which I miss the most are:

• Calc has newly added a feature which is similar to “table formatting” in excel. But the feature behaves very weird IMO (filters dont work, you can’t remove the “total” row).

• I heavily rely on the “smart arts” feature in powerpoint for creating simple visualisations (e.g. to simply visualise an easy process flow). Impress does not seem to have a similar feature.

If just that was true… I am desperately trying to ditch MS office, but LO just isn’t on the same level yet imo :(

If privacy is your concern, then I’d use two different mail addresses / domains. One with your “professional” TLD (mail@johndoe.com) and one wirh your privacy focussed TLD (mail@anon.com).
