Which VPN to choose to watch Netflix from abroad?

You sure Netflix allows VPNs in their terms of service? Honestly, Netflix blocks most VPNs, so even if you find one that works today, it'll probably be blocked tomorrow - it's kind of a cat and mouse game, and personally I'd tell you to check first if your Netflix subscription actually covers international access before you go making things complicated for yourself.

Are you just trying to watch your usual show or do you want to access the catalog from another country? Because honestly, for the first option, VPNs have become a pain - Netflix detects and blocks most of them, like even the supposedly good ones don't work like they used to. If you're really abroad just for a little while, you're better off checking if Netflix offers offline access before you leave, or just connecting to the wifi at a friend's place who lives back home, it's dumb but it avoids all these blocking issues.
