I am finding my tickets through skyscanner regularly. Usually, everything go well.
I also have an experience of being redirected to 3rd party website, which tried to rip me off big time. In that case, skyscanner helped me get my money back.
More details on it:
I was redirected to a website alrehlat.com. My flight was cancelled, thus I needed a refund. However, website alrehlat.com started acting like a scam. They were acting against their terms and conditions, denying information from their call center, refusing to clarify refund process, doing miscalculated refund offers, not replying to my mails.
At that point, I didn't expect to get any money back. I reported this to skyscanner. To my surprise, skyscanner pressured alrehlat to respond to my mails and eventually they secured me the full refund.
