I was excited about trying the Google Experience Launcher because it would respond to "OK Google" on any launcher screen.
However, I was extremely disappointed with the lack of ability to configure the launcher. No, that's too general. There's absolutely no configuration options at all.
One of the things I don't like about the TouchWiz and Google Launcher is that there's no way to control the number of rows/columns and the spacing between them. I use Apex where I can get a lot more rows and columns on the page. And I can control the spacing so I can get icons right up to the edge of the screen. In addition I can reduce the size of the icons for a better look.
It's not like I want to fill the screen with icons, on the contrary, I like to have the icons near the edges and out of the way so I can better see the wallpaper. The TouchWiz and Google launchers are pretty much an iPad launcher. No flexibility and no configurations.
