There's a big difference.

#+begin_latex means "paste this code unmodified in the latex back-end,
and only in the latex back-end". Nothing is evaluated.

With a #+begin_src latex block, depending on :exports parameter, you can
produce something (in this case, probably an image file) and create
a link valid in any back-end, as long as it supports the file format.

Both are possible.
