We reviewed several products before settling on Syncfusion DocIO for our MS Word document creation and manipulation requirements for our team of 20 .NET developers. Our review found the performance and object model of Syncfusion to be equal best along with Aspose Words, and far better than the other options we considered. We ended up choosing DocIO as we already used the Syncfusion Essential Grid and had a good experience with that, and DocIO was also a lot better value. We use several other third-party add-ins and technologies and the really stand-out thing with Syncfusion is the support. Syncfusion first-level support is very fast and effective, and we have found that when patches are required they are usually delivered quickly, with regular status updates from Syncfusion on the progress. I've quite honestly never got this level of support from another vendor and we are now confident that when we discover bugs or require new features that we can work with Syncfusion and rely on timeframes that they provide so we can effectively plan our software releases.
