Me! I have been running nightly for the past couple of months and it is really good. I use uBlock, Res, Ghostery and Imagus. I use Compact and Dark UI mode and it seems more compact than chrome. Also I noticed it consumes a lot less memory, but CPU is 50/50 I'd say. One thing that I find a bit weird is that I find that some Google services work worse, like YouTube eats more CPU than on chrome when it is not maximized and sometimes my connections to google time out for seemingly no reason.
