Tell Me I'm Wrong, Please (Angular and Async)

I'll try and keep this quick. I'm updating one of my Pluralsight courses and I am curious if what I'm thinking makes any sense.

I've been teaching the same approach as most of the other Angular instructors, but I feel like it's not as clear as it should be. Let's look at a simple example of making a network call and showing state. I have a simple view that shows two strings. I am using a central service for calling the remote server with HttpClient. Here's the call using Reactive:

  loadReactive(): Observable<boolean> {
    return this.http.get<ResultData>(this.URL)
        map((data: ResultData) => {
          this.reactiveResult = data.title;
          return true;

In the component, I can just subscribe to the change:

  onLoadReactive() {
      .subscribe(s => console.log("Success"),
        e => console.log("Failure"));

All the nesting makes this hard to read in my opinion. I am thinking of showing the async/await pattern instead. Here would be the call in the service:

  async loadAsync(): Promise<boolean> {

    const result = await this.http.get<ResultData>(this.URL)

    this.asyncResult = result.title;

    return true;

Longer but clearer I think. And in the component:

  async onLoadAsync() {
    try {
      if (await {
      } else {
    } catch {

I plan on teaching both, but is Angular moving away from the subscribe model to async/await now that it exists or are people sticking with it?

Please help me tell the right story to new Angular users!
