HMA

I initially went with HMA because I was looking for a VPN with a huge number of servers in several countries. The product checked this box easily. Apart from this, the setup is quite simple.

On one or two occasions, I noticed that some server locations as shown in the software were actually different from what IP checkers reported. Some of the IP addresses are also blacklisted, but this is a general problem with most VPNs.

HMA has plenty of IPs available for almost all countries in the World and keeps no logs of any of them, it is totally secure and very fast.
It has all the feature a standard VPN should have including kill switch, Cross-Platform Support, one-click connect and disconnect, and so on.

Only a few locations in the USA, Canada, and the UK work perfectly, selecting a city in the USA might end up with you having the IP of Czech Republic and this is the same with some of the P2P enabled locations.
It is best to verify the IP and Country for each location so as to be sure.

Privacy; this is a bit tricky as from my perspective, this part of the vpn is both an advantage and a disadvantage depending on where you are coming from. The intetnet privacy collects some sort of information that will be detailed in the cons but the good thing is, they never track your usage and the websites you visit and that is some sort of privacy you paid for.
Speed; depending on whether ypu are using the service on a smartphone or a personal computer, there's never that slugiish feeling that comes with using free vpn trials, your internet connection is as swift as ever, only that now you're shielded from every prying eyes that's interested in what you do on the internet.
Simplicity; hma's ease of use can be compared to no other as just about anyone can get around the interface to get to their various needs.
Vastness; hma deserves all the accolades when it comes to the available servers presented to you to choose from, there's a lot of vpns out there with promises of a wide selection of servers when you upgrade to their subscription based service, at the end of the day, what you get is not usually what you paid for.

Pricing; in all sincerity, to some class of people, the pricing of their services is fair but to others, it's not so fair as there are other alternatives with cheaper subscription fee, the company will do better for themselves to review the pricings.
Extended options; there's little to no provision for power users who use vpns for more thsn bypassing restrictions on multimedia websites, some of us use vpn for accessing our funds on online payment systems who are strict on how you access your account, a slight change in your ip address can ruin years of hardwork as cash of many has been stranded cause of this oversight
PC user interface; the ux team must be headed by someone who is as lazy as lazy can get as he somehow maneuvered his way to port the smartphone interface on personal computers and it is an eye sore.
Privacy; with hma you don't have all the privacy you paid for as some information that might make you uncomfortable is being collected as you surf the net
