Disagree on the semantics. Physical realities are concepts as well. “Energy”, despite being an extremely useful physical measurement, is an abstract concept. “Physical realities” and “concepts” are not mutually exclusive nor antonymous words.
In this case, the Aries/vernal point is a concept used to define coordinate systems using physical measures from Earth.
I think it depends. In my case, I write faster in LaTeX as the formatting is done a lot quicker. Just need to find one template I’ve already used and is aproppiate for the ocassion.
Although being able to take a screenshot and paste it is a huge bonus and time saver in LibreOffice when taking notes in real time.
