Excellent points. Asking which is "more powerful" requires context to make the question proper. So many questions in computers are answered by "In Depends". This has gone back to since when computers were first invented--different computers were designed to run best with different applications. To this day, while a great many computers are general purpose, there still is a need for certain specialty machines for specialty applications, such as the supercomputers used at Los Alamos.
