I'd stick with Netflix US, mainly because the content we get in the local version may be limited and most likely get censored version as well. If you are already watching Netflix then you will get what I mean...hahah.
Actually there is no need to use VPN if you just want to view Netflix. The previous post above already showed its possible to configure UnoTelly DNS to access Netflix. I'm not sure how UnoTelly authenticate users but it appears that theirs work as open DNS resolvers.
You can try configure your device(PC/laptop/tablet/media box) DNS to 122.248.238.233 and try accessing
www.netflix.com before and after to see the difference. If you are accessing from multiple devices, eg. casting to Chromecast, then will need to configure the DNS on the router.
