The uniq in the Blade and Blade 2 have a 3" voice coil and multiple other considerations intended for hi power handling and high output with low distortion unique to any of the other models before or since. Like most speakers in their price range they respond to components driving them so could sound amazing or just average(for the money) depending on the individual component matching.
On a budget the ls60 is the safe bet but the ceiling can't compete with what the blade's can do when a systems built around them.
