I think hiribi.com is quite legit. I did first sell with them on 2017-02-27 . Since that time i sold them many btc together 7.36 BTC. No chargeback . Still some can come as there is 180 days for CB to be done. But i really doubt as they are really responsive and they are evolving in time . They keep all transaction tracking under your dashboard. Ordinary scam pages looks different .
I would say that they are 100% legit once my first transaction will be older than 180 Days.
Its true that their Service start using many people now and they are quite slow with payment. But they promise that they will improve payout times really soon.
Paypal is risky money procesor , but you can manage the risk even as seller if you know how
