Sasuke's use of Blaze Release is very much different from Madara's use of Storm Release. Blaze Release has always been associated to the Sharingan and Amaterasu. It's almost like Blaze Release is to MS what MS is to the regular Sharingan, a special skill within it that few can achieve. We also know there has been at least one other user of Blaze Release, per Tobirama's comment. Storm Release has no such association with the Uchiha.
