The main advantage is that ECE is generally covariant in all sectors, and is developed in four dimensions. ECE is already being used for engineering and start up of new companies, while string theory is unable to predict anything that is not already better and simpler known by ECE theory. The latter can be applied to phenomena of all kinds, for example non-linear optics, in which string theory cannot be applied. String theory grew out of particle and field theory, and is still largely confined to that area of physics after about forty years of trying to predict anything that is really new.
In five years, ECE theory has been applied to all physics and chemistry, and also to many aspects of electrical engineering. String theoery is not used at all in chemistry and engineering, and is not used in physics except in specialized circumstances. String theory carries with it all the flaws of standard general relativity, so is no advance on 1915. In particular, string theory neglects the Cartan torsion.
