NordVPN

Friendly interface, Kill Switch (it cuts internet when not connected to VPN), 5500 servers worldwide, works in desktop and mobile.
NordVPN has a very competitive price and frequent updates.
You'll have split tunneling, which means you can optionally choose which apps use VPN-protected connections.
Onion over VPN for enhanced privacy and anonymity - that goes slow, of course, but onion goes slow by its structure.
Some less popular functions are still included, like custom DNS or invisibility on LAN, and there is an option there to block ads and malicious websites.
I didn't use that last one, but it might be tricky as it is unclear how it works, so I have it disabled.

Russia is out. They have 5500 servers, as they say, but there is not even one in Russia.
Not everybody needs Russia; however, it's not there.
Sometimes it's not connecting automatically on computer startup. However, if you have the kill switch enabled, it's not connecting until you enable it manually, so you're protected.
2- The Split tunneling seems that doesn't work with all apps. For example, I tried to let the signal connect directly but can't. The same problem is with some other apps. But that might not be NordVPN's problem because some 'foxy' apps like WhatsApp are build to bypass VPN and connect directly.
3 - They had one server hacked for one month. Press was pointing that as a substantial significant deficiency BUT, that isn't a problem at all. First of all, it was just one server out of 5500 servers which is equal to nothing.
And - in the end, the majority of sites already have HTTPS, so what a hacker might see is, the IP [whatever] - is connected to [Amazon].
There is no sensitive information to be leaked.
