In Brazil, electrical connections are almost always done splicing electrical cables by twisting the strands together and insulating them with electrical tape. [Here is a video](https://youtu.be/Y9TrJhAGcoA) showing some of the connections the way they are done in Brazil. Terminal blocks are only used on some specific applications and wire-nuts are nonexistent here.

Here on DIY.StackExchange and elsewhere, I've seen criticism of that method and statements that wire-nuts are the way to go.

Is a stranded cable connection, twisted and taped as shown in the video, objectively any better or worse than wire-nuts/terminal blocks?
