FWIW: I'd not say $tan$ and $cot$ are "best", but they are the notation that more people understand than $mathrm{tg}$ and $mathrm{ctg}$. So, if you're writing for a wide audience, you might consider using the more popular ones.

In current US textbooks, $tan$ and $cot$ are commonly used and standardized. Also: $sin, cos, sec, csc$. In other countries, and in the 19th century, you will find others.

Standard
ISO 80000-2 Quantities and units — Part 2: Mathematical signs and symbols to be
used in the natural sciences and technology
is perfectly clear: the right symbols are $tan x$ (item 2-13.4) and $cot x$ (item 2-13.5).
To cite the standard: "$text{tg } x$, $text{ctg } x$ should not be used."
$endgroup$
$begingroup$
+1. Do you have a source for the ISO passages? The only thing I can find on ISO.org is an unhelpful preview and a link to purchase the document; perhaps I didn't look hard enough. The Wikipedia "ISO 80000-2" entry only makes passing reference to "sin" and "tanh" (and "arcsin" and "artanh"). (Interestingly, the entry reports that "$sin^{-1}$" and "$tanh^{-1}$" aren't included in the standard. I'm not sure what to think about that.)

@Blue I have access to these standards. They are rather expensive, so their publisher is doing everything it can to disable free access. If you have a specific question I can look into standard for you.
