Depends on how you look at it. With "family" based immigration, someone has basically vouched for your character. In the US, family means you are financially responsible for this person being let in this country. If they can't fend for themself, you shelter, clothe, and feed them. They are really serious about it and it requires you meet income, savings, and property thresholds.

The UK sort of has both, family and skills can get you in. Recently, they have started to de-emphasize the family visas.

With points, you are at the mercy of the market of the host country. The UK has, recently, restricted the high-tech industry in some areas, but hairdressers are still in demand under the points system. So someone with a BSc may actually be less qualified than someone that went to beautician's school under this scheme.

I always wondered how that works. For example, my great-grandmother from my father's side was born in Brooklyn. And then they have decided to return to Europe. I must be one of the few that has heritage reversed.
