Nope. I was using uBlock origin on Firefox with dynamic blocking and quite a bit of the provided blacklists enabled. I just gave quick uMatrix a look, and it does not seem fundamentally different to me. I like that I can easily add some globs and use version control on the blocklist without having to import-export my settings.
Qutebrowser is a very interesting browser. It's easily scriptable using a config file in python, but not only. It has a nice Emacs Customize like UI, and then it has a system reminiscent of CGI for running external scripts against web pages or on events. A definite improvement for me over whatever is available. I maintain a handful of websites with js enabled (HN, reddit, youtube, a couple more), and for the web apps I'm forced to use, I just start up Chromium temporarily. It's been lovely so far.
uMatrix works quite differently than uBlock, and the interface is much easier IMO. It also lets you manually edit rules by text if the GUI doesn't work out. For example, the following lines blocks any third-party loading of anything from Facebook or Twitter, but allows Google Fonts and Gstatic to load except for cookies
