It really is like the name implies. I tried so many brands of solder wire but only Best makes it past all the categories of my test which includes melting temperature, flow and balling ability and shinyness after setting. Only drawback is that it's not cheap which is why I am using mainly the 2nd best choice which is Ultracore. It's reasonably close to Best quality but without the high price.
