I'm looking to write a progressive desktop web app along with a progressive web app for mobile, given the variety of mobile browsers, what's the best sdk to use?

Selection of the SDK will depend on your app requirement. I would recommend you to go through Kinvey's documentation on following link:
Yes, Kinvey HTML5 SDK is compatible with the list of browsers mentioned on the Github link. It is recommended to use the browsers versions mentioned on the link.
