Inline or Code Behind - EPI Server Property

I have a requirement where a product price is selected based of discount flag setting done by web admin in edit mode. I have three property's “Normal Price”, “Promotional Price” and a flag “For sale”. if “for sale” is on then the promotional price should be shown other wise normal price should be shown.  I found two ways to work on this issue inline or code behind.

Code Behind :-

For code behind I created a property and made a check in get assessor of the property -

 public int Price
        {
            get
            {
                PropertyData property = CurrentPage.Property["StockStatus"];

                if (property.ToString().ToLower() == "forsale")
                {
                    PropertyData property22 = CurrentPage.Property["PromotionalPrice"];
                    if (property22 != null && !property22.IsNull)
                    {
                        _price = Convert.ToInt32(property22.ToString());
                    }
                }
                else 

                {
                    PropertyData property22 = CurrentPage.Property["ProductPrice"];
                    if (property22 != null && !property22.IsNull)
                    {
                        _price = Convert.ToInt32(property22.ToString());
                    }
                }

                return _price;
            }

        }

Only html at UI is-

<% = Price %>

Inline Code:-

Below is the straight forward inline code -

<% if (CurrentPage.Property["StockStatus"].ToString().ToLower() == "forsale")
   { %>
       <%=  CurrentPage.Property["PromotionalPrice"].ToString() %>
<% }
   else
   { %>
         <%= CurrentPage.Property["ProductPrice"].ToString() %>
<% } %>
