Overhyped IMO. Most strings feel very similar, and a ton of companies wind their own strings. D’Addario goes even further and draws their own wire for some strings, e.g. NYXL, XT, XS. Those strings do feel noticeably stiffer to me than most strings, and it’s probably because the wire is different.
I play Kahlers though. The biggest factor for me liking a string is how rugged the ball end twists are, since the cam puts a beating on them. NYXLs have a “fusion twist”, which just looks like they solder them at the factory. They hold up far better than any other string for me as a result.
To be fair, I haven’t given EB Paradigm a shot yet. They supposedly do something similar to reinforce the ball end twist
