title: ExcelDnaUtil vs Interop.Excel
body: <p>I am currently comparing Excel-DNA vs VSTO and Interop. I am interested in creating an Add-in for Excel using C#. I don't need to create UDF's, but only interact with Excel, ex: read cells, write cells, create sheets, etc.</p>
  
  <p>Which solution would be better for this: Excel-DNA or VSTO?</p>
  
  <p>Thank you.</p>
