I wouldn't say it's inferior. There are some nice things about it (written entirely in TypeScript and uses RxJS and Observables) and it's more of an opinionated framework rather than just a set of libraries.
Another bit that rubbed me the wrong way about A2 is all the uber-magical stuff going on and all the pitfalls it created. Trying to understand why you need to put an @Input() on targets but not sources and what the actual consequences of that are took me way longer than I care to admit.
