Fantastico is certainly a great tool to install difficult scripts with a single click. You can save time and you won't have to install the scripts manually if you have Fantastico
There are other addons and tools which can install some applications and scripts with a single click, however, those addons aren't successful enough and hence users do not prefer those tools :( When it comes to Fantastico, it is very successful in establishing itself as a one click installation tool and hence users like Fantastico
