I still can't shake the feeling that it's only a matter of time before Moloch gets to them and they'll start serving crapware like any others. I'd love to be wrong on that.
Ninite is a really greate tool I've used it countless times while having a student job at our universities user support from 2010-2013.
I really hope their business model (selling an update tool to private users and a side-wide deploy tool to businesses) works out until there is a usable windows store / package manager around.
Each time I have to help someone setup a new windows laptop I get reminded why I'm using Linux as my main OS ;)
I know ninite has been around for at least a few years. I've used it and it was an excellent UX. One installer, go through the wizard, then sit and watch it install a dozen useful things for you without having to hunt down all their installers and carefully click through, unchecking, canceling, backing through, and skipping around the horrible installers most of them have.
Ninite is quite good; I've been using it for years. At one of my old jobs (a local PC repair shop), we were even in the process of switching our custom install script to a Ninite package.
Chocolatey used to mostly be OSS stuff, but it looks like they've expanded with some nerd-favorite proprietary stuff now too. The list is also moderated, so that's a good sign.
I can't speak for the other two, but I believe Chocolatey is being integrated (or vice versa) with OneGet, the built-in package manager for Windows 10.
