We currently use Private Internet Access for my small business and it’s generally been good, although sometimes the DNS is slower than my ISP DNS. Setup was very easy on iOS and OSX and Windows 7, 8 & 10.
RE Exit points: Australia (Sydney and Melbourne) work well but if you want somewhere overseas then I’ve found Hong Kong is quick. The US is variable but generally ok and the UK is a bit slow. Other than trying the other locations just to see how well they work I haven’t spent enough time using them to express an opinion about their average performance.
Before that we were using IPVanish and whilst it worked well I found setup to be more difficult and complicated.
I can’t comment about any of the other providers.
