What difference does ion-list make?

Ionic Framework
1

Hi, i would like to know if ion-list provides any usability or performance improvement over not using it. Im asking because im able to scroll over my content even without putting it inside ion-list and using Google Lighthouse for profilling i discovered that ion-list takes 1sec more to load than putting my content direct inside ion-content (not in this small example, but in a real project).

For example:

<ion-content>
 <ion-list>
          <ion-card ng-for="let item of list">
              
                <ion-card-header>
                  {{item.title}}
                </ion-card-header>
              
                <ion-card-content>
                 {{item.desc}
                </ion-card-content>
              
              </ion-card>
    </ion-list>
</ion-content>

Is any faster or has any advantage over:

<ion-content>
          <ion-card ng-for="let item of list">
              
                <ion-card-header>
                  {{item.title}}
                </ion-card-header>
              
                <ion-card-content>
                 {{item.desc}
                </ion-card-content>
              
              </ion-card>
</ion-content>

Thanks in advance.
