Mathbf, cause we’re best friends.

Arrows are more descriptive. \vec is better.

If you like mathbf more then at least redefine vec and use vec. Keeps the code more tidy.

Neither, I just write a symbol.

\mathbf{} cause I can just use Ctrl+B on overleaf.

\mathbf. It’s consistent with \mathrm for well-defined constants

No idea what this is but /vec is easier to write so I choose you Pokémon /vec

I haven’t heard those names in a long time…
