Create cPanel for subdomain

Let's say you have a domain called "example.com". You want to create a subdomain "guitar.example.com", and you want the subdomain to have its own cPanel.

Basically there are 2 ways to create subdomain:
1. Using cPanel.
2. Using Web Host Manager.

What's the difference?
When creating subdomain using cPanel, you will not get a new cPanel account.
So, to upload subdomain's files, you have to login to cPanel using the parent domain account. This is problematic if you want to create subdomain for your customer.

However, if you create subdomain using Web Host Manager, you will get a new cPanel account. So, you will only be able to access the subdomain's files when you login to the subdomain cPanel.
