I like the mVDP form and the JIRA integration the most, in addition to the basic features, they are useful for me.

The Hackrate platform is easy to use and provides a great coverage to discover vulnerabilities in software. They are continuously expanding their researcher community.

The implementation was fast and seamless.

Decent but it can't be only way to work in bug bounties. I would have to work on other platforms like intigriti, bugcrowd, etc. to sustain my income.

My overall experience is absolute positive. They have professional analysts with short response times. Also they provide decent amount of reward for the bounties, and the reputation / badge system is well designed. Also for companies, who want to know their assets are safe, this opportunity provides reasonable assurance, because of the numerous userbase will make sufficient work on the targets.
