GroupDocs vs Aspose Pdf

My customer asks me what’s the different between GroupDocs vs Aspose Pdf, which one better for advanced application?

Need your advice, many thanks in advance.

GroupDocs doesn’t has a dedicated PDF manipulation API (e.g. adding bookmarks, creating PDF programmatically from scratch, add form fields, delete form fields).
However, you may need to take a look at Aspose.PDF API features.
Could you please share your PDF implementation or use-cases with us? We’ll then guide you accordingly.
