No. I dont agree that the 1521 is more efficient than the 1515. A bigger motor spinning at the same rpm as the shorter motor will draw more current and give shorter run times.
Yes... the 1521 can make more power than the 1515, but the power if for nothing but spinning wheels. You cant put it to the ground. (you cant even put all the power of a 1515 to the ground)
I'm assuming based on you first post you want to keep some kind of decent run times and the 1515 will generate enough power and speed to make you very happy. On the other hand if you want flat out raw power and current draw and run times be damned than theat 1521 would sure be fun. There is something to be said for overkill...
