For me the biggest inconvenience of \(·\) is that it's tedious to type. On my keyboard, M- S-8 M- gives me \(\), compare to M-4 M-4 (which I could probably limit to M-4 with electric-pair-mode). Thus, I use $·$ by default. I usually just rely on whether my expression get the colored by org-latex-and-related. In most cases that's a good indicator, but it does not work with ($x$). —Rasmus -- With monopolies the cake is a lie!

Thanks for the pointer.
Given that there are 'exceptions' already I'd like to see that last
sentence extended to 'followed by whitespace, punctuation, a closing
parenthesis or a dash'.
Especially since the \(...\) notation is particularly hard to read when
enclosed in parentheses. For example (\(\frac{1}{2}\)) as opposed to
($\frac{1}{2}$)
But as I said earlier, this is a minor nuisance and I am happy to resort
to \(...\) whenever necessary.
Thanks,
Andreas

Thanks. A very good read. These are arguments on the LaTeX end. My question was more on the orgmode end, I guess.

The fact that both org and MathJax deal better with \(...\) just reinforces that choice. I do not agree with the readability but I can live (quite happily) with using \(...\).
