i like aurelia because it has a minimal footprint on my code.

i set up routing with the views available and i write a class for each view. there is practically no boilderplate code. (eg what is $scope in angular is simply the class object itself in aurelia)

any class level function and variable is automatically made accessible from the html template. classes and templates are linked by sharing the same name: welcome.html, welcome.js, export class Welcome ...

while in angular you have to declare everything explicitly, aurelia mostly just figures it out by itself.
