OpenBox, IceWM and Fluxbox are far from the only floating window managers. I use KDE/Kwin and I'm pretty happy with it.
The article is super short and doesn't contain relevant information. Maybe try to include more text, more images, generally more of what people like to read. Currently your blog doesn't contribute much to the general Linux ecosystem and is just another noob-focused rehash of stuff seen elsewhere.
If I wanted to find out what the best stacking/floating window manager is, I'd just look at the Arch Wiki page on window managers and open their respective home pages. You didn't even include screenshots, nor did you include example configuration, just a short rundown.
