Thats the best way but I've never had trouble with twisting and taping. If done correctly, it will last a long time. It just looks like a hack is all
Yeah, define "a long time".
I have had many taped splices do 1 of 2 things after about 2 years. Either the tape gets all sticky and makes a mess that you don't wanna deal with, or the tape falls off.
I will say that if you must use the twist and tape method, be sure to use GOOD QUALITY TAPE (3M tape as the reference article mentioned). If you use Harbor Freight tape, you might be redoing the splice in 6 months.
On the other hand, solder and heat shrink is PERMANENT. I have also made splices so good and precise with this method that you would only notice it from very close inspection.
To me, it comes down to "more work and do it once or less work but repeat the work at a later date". Granted, not everyone has access to the tools to do the solder method. But, I consider soldering iron and heat shrink as necessities!
Hey, there is another option not mentioned in the article, and not mentioned here yet. In some situations, this could work out very well. I present the humble terminal block.
