Benefit: FULL control panel with custom resolutions, more control, usually NEWER, support for more games, more apps, bug fixes.
Negative: Not supplied by MS, not updatable through Win Update. May not have specific battery customizations that MS may or may not add to drivers, every firmware from MS, you have to reinstall manually again...
For some reason every version of Win10 has only given me the Microsoft Basic Display Adapter and not Intel HD Graphics. When it does the MS BDA I cannot adjust brightness. When I install the Intel ones Windows Update doesn't replace them either with the May Firmware update. These are clean installs.
