I'm a professional reviewer of VPNs (among other things). I'm afraid it's impossible to name one "best performing service" as that depends on factors such as which ISP you're using, where you're located, where the server is that you want to use, and what load it's under at that time.
However, I can tell you that in my tests Express VPN, Hotspot Shield and IPVanish all had very decent performance and successfully unblocked all the streaming services I tried, namely BBC iPlayer, ITVX, Channel 4, Now TV, Netflix US, Disney+ US and Hulu.
