As others said, ProtonVPN is a really good VPN. The paid version is well-studied and they were CERN/MIT scientists so I mean, it's not surprising. Servers in Switzerland are probably a good bet if you want to go for privacy, any other case just depends on where you actually are. They also have a free version which works well even though you have much less servers to choose from and they are, obviously, more crowded. No problems anyway, streaming goes fine so you shouldn't have any complaints.
