I have extensive experience with two, so FWIW:
I purchased a lifetime 5-device license for VPN Unlimited a few years ago when it was on sale. Had issues with frequent dropped connections, multiple times a day, with disruption of my online work each time. I patiently waited through 4 or 5 "New, Improved" versions without the issue ever getting fixed (they always blamed the problem on me, or at least my configuration choices, which I did not make - I used the recommended defaults) and finally gave up & abandoned it. Should have done so much sooner but, hey, I had a lifetime deal. Because of the frequency of dropped connections, I don't recommend it for extended periods of use. Might be OK if only short intervals of use are needed. Having not used it in a couple of years, my information may be a bit stale, however.
After some due diligence, I purchased NordVPN a couple of years ago. It has been a solid, reliable workhorse and dropped connections are exceedingly rare. Reasonably priced, well-reviewed and happy to recommend it. Even though sounds like it would be a Scandinavian outfit, I understand it is based in Panama.
