angular1 vs angular2-now

angular1.js

angular.module('app').controller(['$meteor, $scope', function() {
  $scores = $meteor.collection(Scores).subscribe('scores');
  $scope.amount = '';
  
  $scope.insertScore = function() {
    $scores.call('insertScore', $scope.amount);
  }
  
  $scope.resetAmount = function() {
    $scope.amount = '';
  };
}]);

angular2-now.js

@Component({selector: 'create-score-form'})
@View({templateUrl: 'client/scores/create/create.ng.html'})
@Inject(['ScoreService'])
class CreateScoreCtrl {
    constructor(ScoreService) {
        this.service = ScoreService;
        this.amount = '';
    }

    insertScore() {
        this.service.insertScore(this.amount);
        this.resetAmount();
    }

    resetAmount() {
        this.amount = '';
    }
}

angular2-now.scores.js

Scores = new Meteor.Collection('scores');

if (Meteor.isClient) {
    @Service('ScoreService')
    @Inject(['$meteor'])
    class ScoreService {
        constructor($meteor) {
            this.$meteor = $meteor;
            this._collection = this.$meteor.collection(Scores).subscribe('scores');
        }

        findAll() {
            return this._collection
        }

        @MeteorMethod()
        insertScore(amount) {
            this.$meteor.call('insertScore', amount);
        }
    }
