Dapper vs ADO.Net with reflection which is faster?

I have studied about Dapper and ADO.NET and performed select tests on both and found that sometimes ADO.NET is faster than Dapper and sometimes is reversed. I understand this could be database issues as i am using SQL Server. As it is stated that reflection is slow and i am using reflection in ADO.NET. So can anyone tell me which approach is the fastest?

Here what i coded.

1. Using ADO.NET

   DashboardResponseModel dashResp = null;
   SqlConnection conn = new SqlConnection(connStr);
   try
   {
       SqlCommand cmd = new SqlCommand("spGetMerchantDashboard", conn);
       cmd.CommandType = CommandType.StoredProcedure;
       cmd.Parameters.AddWithValue("@MID", mid);
       conn.Open();
       var dr = cmd.ExecuteReader();
   
   List<MerchantProduct> lstMerProd = dr.MapToList<MerchantProduct>();
   List<MerchantPayment> lstMerPay = dr.MapToList<MerchantPayment>();
   
   if (lstMerProd != null || lstMerPay != null)
   {
       dashResp = new DashboardResponseModel();
       dashResp.MerchantProduct = lstMerProd == null ? new 
       List<MerchantProduct>() : lstMerProd;
       dashResp.MerchantPayment = lstMerPay == null ? new 
       List<MerchantPayment>() : lstMerPay;
   }
   
   dr.Close();
   
   }
   
   return dashResp;
   
   

2. Using Dapper

   DashboardResponseModel dashResp = null;
   
   var multipleresult = db.QueryMultiple("spGetMerchantDashboard", new { mid = 
   mid }, commandType: CommandType.StoredProcedure);
   var merchantproduct = multipleresult.Read<MerchantProduct>().ToList();
   var merchantpayment = multipleresult.Read<MerchantPayment>().ToList();
   
   if (merchantproduct.Count > 0 || merchantpayment.Count > 0)
   dashResp = new DashboardResponseModel { MerchantProduct = 
   merchantproduct, MerchantPayment = merchantpayment };
   
   return dashResp;
