A good point. Alternatively I could write error handling myself or
include a library/class. This is where, in my opinion, Smarty shines, but
is not significantly different than other libraries/classes.

I was waiting for someone to ding this :-) I have been used to using
<?php echo $variable; ?>.

Another good point. But by writing it myself or including some other
library/class I could have the same functionality. There again, Smarty is
a great library, and I'll use it when I need it.

Me too. It's likely I'll use it in the future.
