PDFTron demonstrated superior speed and functionality out-of-the-box. In contrast, the competition took a lot of shortcuts, and it was obvious in the user experience. If we were to swap another SDK in for our current one, I would expect customers would definitely notice a difference, which in turn could affect our customer retention.
