IronPDF vs Aspose.PDF vs Syncfusion：我應該選擇哪個ASP.NET PDF程式庫？

using Aspose.Pdf;
using Aspose.Pdf.Text;
// Create new document
Document document = new Document();
Page page = document.Pages.Add();
// Add formatted text
TextFragment title = new TextFragment("Invoice #INV-2024-001");
title.TextState.FontSize = 18;
title.TextState.Font = FontRepository.FindFont("Arial");
page.Paragraphs.Add(title);
// Create table
Table table = new Table();
table.ColumnWidths = "200 100 100";
// Add header row
Row headerRow = table.Rows.Add();
headerRow.Cells.Add("Item");
headerRow.Cells.Add("Quantity");
headerRow.Cells.Add("Price");
// Add data row
Row dataRow = table.Rows.Add();
dataRow.Cells.Add("Professional Services");
dataRow.Cells.Add("10");
dataRow.Cells.Add("$1,000");
page.Paragraphs.Add(table);
document.Save("invoice.pdf");
