inputstream adaptive, drm, netflix and amazon vod support are the most important reasons for me. Finally a good way to watch netflix (1:1 pixelmapping, framerate switching, hq decoding, fast interface). LE 9 / Kodi 18 was for me the reason to finally get a netflix subscription. Just works out of the box, no need to tweak funky patches, just download a few add-ons and you're ready.
And other than for streaming services. Any benefits over Krypton?
