I've used a few
cheap vpn services - but opted to NordVPN for the pricing.
Depends what you prefer. In terms of security - they will both be almost the same.
I do find some servers on Nord a little inconsistent at times but it's very few and far between.
The other bonus is NordVPN have been jamming it with new features often - and now I have an incredibly intuitive, feature rich and efficient VPN. Ultimately though - NordVPN is by FAR better value IMHO. That and their support is great.
Whilst I don't think there will be significant difference between the the other cheap vpn services like surfshark - Nord beats on price hands down in the USA - and I'm a very happy long serving NordVPN user.
