For many years, I've recommended AirVPN, Insorg, IVPN and Mullvad. And formerly BolehVPN and PIA. There was chatter about BolehVPN's logging policy. And now about PIA's acquisition by a firm with an iffy reputation.
Those are all relatively old, compared to mainstream VPN services. So there's been more time for bad news to come out.
I've also used older ones, such as Cryptohippie and Rayservers. They're among the first OpenVPN-based services. Cryptohippie used to be quite expensive, with a ~low usage limit. But now its price is comparable to many others, and I don't see a usage cap. It's not as fast as many others, but arguably far better secured against adversaries.
Rayservers is extremely old school. They only accept gold-based electronic currencies (Truledger and Loom). Those are pre-Bitcoin. I'm not sure whether they still work.
There are others that I use. But I'm not going to talk about them.
