All those rankings (Top5, Top10, tip-top etc.) don"t always represent the real state of affairs, that's why i don't like them. I believe the best way out is to test everything personally, though it requires some time & efforts, but after such personal tests, it's easier to share better & more true-to-life information on the topic. As for me, I employ Privatoria.net services (https://privatoria.net/) & I'm satisfied :)

My favorite VPN provider is Privatoria https://privatoria.net/ Absolutely reasonable pricing, one-click registration, no logs stored, got servers in 63 countries, plus their service of "doubled security" - VPN+Tor. I sure like it a lot! :)
Nice work! I recently read about a new VPN Service i'm very interested in, but i didn't have time to try it yet.
Its from the Czech Republic: https://privatoria.net/
It's pretty new, i think, so not a lot of servers might be a problem. But they increased the servercount since last time i visited their site.
