is there any difference between
```\end{tikzpicture}\hfill%
\begin{tikzpicture}```
and
```\end{tikzpicture}\hspace*{\fill}%
\begin{tikzpicture}```
?
I've read this https://tex.stackexchange.com/questions/45948/what-is-the-difference-between-hspace-fill-and-hfill
but i can't see a difference. would it maybe better to use `\hspace*{\floatsep}%`? what's the "most correct" one?
