Looks nice, but I would always prefer Chocolatey (https://chocolatey.org/packages). Reason: More (and easier to customize) packages / applications to get.
Ninite has the advantage of being self-contained in a single executable, though. Chocolatey looks like something you have to install, which makes it poorly suited for quickly installing something on a machine that's not yours.
Chocolatey is like apt for Windows. It is worth the install.
