I agree. NordVPN is nice most of the time (at least for me), but its UI is clunky and incredibly slow when searching for a particular server. I've also been experiencing major connection issues over the past few months, so that's been annoying to say the least.
I was with Private Internet Access before and will either switch back to them or possibly to TunnelBear in the near future I think. The last 6 months with NordVPN has been pretty terrible.
