Hourly pay is when you get paid by the hour. Commission pay is based on sales. Salary pay is large payments made in either monthly or yearly intervals. Personally, I prefer hourly pay.

With hourly pay, you usually get paid weekly/biweekly, and you legally have to get paid for any overtime you work, as you are not contracted in to a set amount.
