Don’t want to be rude, but as long as you can’t figure out by yourself if you should not put money into something you are probably don’t require it. It is part of the capability to understand the difference between tools and whether you require a payed version or not (for now)… In the end the tool does not decide whether you are good skillwise or not.

You can use ZAP's automated scanner to find low hanging fruit. The manual option isn't bad either. Think of Burp as a more manual tool and ZAP as an automated one (to some degree). More on reddit.com
