REFACTORING-SkinnyModel.rb

#Let's take a look at the welcome method of the User model. 
#This method is doing way too many things, 
#you really need to split it up into separate private methods.

#Create the following private methods: 
#send_welcome_email, enable_welcome_tour, enable_welcome_promotion. 
#Then move the code from the welcome method into each one. 
#Make sure to still call each method from within the welcome method.

class User < ActiveRecord::Base
  def welcome
    # send_welcome_email
    WelcomeMailer.welcome(self).deliver

    # enable_welcome_tour
    self.welcome_tour = true
    self.save

    # enable_welcome_promotion
    promo = Promotion.new(name: "Thanks for joining!")
    promo.set_redeemer(self)
  end
end

SkinnyMode-step1.rb

class User < ActiveRecord::Base
  
  def welcome
    send_welcome_email
    enable_welcome_tour
    enable_welcome_promotion
  end
  
  def send_welcome_email
    WelcomeMailer.welcome(self).deliver
  end
  
  def enable_welcome_tour
    self.welcome_tour = true
    self.save
  end

  def enable_welcome_promotion
    promo = Promotion.new(name: "Thanks for joining!")
    promo.set_redeemer(self)
  end
end

SkinnyMode-step2.rb

class User < ActiveRecord::Base
  
  def welcome
    UserWelcome.new(self)
    UserWelcome.welcome
  end
  
end


class UserWelcome
  attr_accessor :welcome
  
  def initialize(user)
    @user = user
  end
  
  def welcome
    @user.class.transaction do
      send_welcome_email
      enable_welcome_tour
      enable_welcome_promotion
    end
  end
  
  private
  
    def send_welcome_email
      WelcomeMailer.welcome(@user).deliver
    end
    
    def enable_welcome_tour
      @user.welcome_tour = true
      @user.save
    end
    
    def enable_welcome_promotion
      promo = Promotion.new(name: "Thanks for joining!")
      promo.set_redeemer(@user)
    end
end

What benefit does moving the logic into a UserWelcome class have over the 2nd file? 2nd file seems cleaner in my opinion
