Installing WordPress through the cpanel is the easiest because the one click installer app already make it easy for you to complete the installation in just one click. But for a newbie to install the WordPress manually by FTP, it can be quite confusing. I always have problem in the part that involved creating a new MySQL Database and assigning User and then to wp-config.php.
