Well, I admit to being a bit biased here - but I think I can still safely say that you will find Create Fillable PDF Create Fillable PDF Reader the best alternative to the native Windows 10 PDF reader. Create Fillable PDF Reader supports the full PDF 1.7 (ISO 32000 131) specification while being the fastest to open & view of the product you 19ve listed. It also better integrates with the operating system to enable PDF integration more deeply in places such as Explorer and Outlook.
