Note also that some languages and keyboard layouts don't favor the use of
the backticks for this case. In Spanish keyboards, this characters: `´^¨
are dead keys (I think that's the correct term, not 100% sure), which means
they don't print anything until you press another key. That means that to
write `foo` I have to actually type `[space]foo`[space], or at least
``foo`` (press the key twice). An in any case it's just a matter of tastes.
Besides that, $() is far clearer, and it allows you to do things like this:

echo $(ls -l $(which tar))

Just an useless example. That, you can't do with backticks.
