I have a smok alien, an Osub 80, and an Osub King. They all work fine. Only issues are the King faded badly and the paint wore off on the Alien. I've had no operational issues with any of them. I've had far better luck with them than Wismec or Kanger. Either way, they're all cheaply made and priced products. You can't expect too much out of a starter kit that runs under $100.
I think you can narrow it down with what you posted. smok is the most widely available line. Thus, you're bound to find more people who have used them. As a result, you will find more people who have had issues with them. So they get a bad reputation online, but amongst newbies who don't research they are popular because they work about as well as anything else.
