As far as I know Nord VPN offers a lot of servers and is considered as the VPN service that offers the most variety of servers but I think if you are more concerned about privacy and security then I think Mullvad VPN is a better choice with open source.

Yes it's cheap but there are other VPNs like express VPN that give you good discounts if you buy their yearly subscriptions etc but still, they cost you more than 5$ a month. However, I just wonder why they aren't as popular as Nord or Express VPN? Do they (express/nord) offer extra services etc
