I gave Vivaldi a go because I wanted to speed up the testing of a website 'logged in' (with Chrome) and 'not logged in' (with Vivaldi). Vivaldi was notionally perfect for that with the same F12 tools as Chrome. I could delete session cookies and do my testing with it, no learning required.
So I would say I have given it a fair shot. But what browser am I using now? Chrome. Sometimes when you want to get something done you don't need to find that the maximise/minimise buttons are somewhere different, and with Ubuntu/Unity + Vivaldi they are - 90's style, in the top-right hand side.
I was actually a late convert to Chrome, for a long time I 'needed' Firebug and found the Chrome F12 tools to be inferior, or with a learning hurdle. With Vivaldi there is no leap of re-learning required, but, it doesn't have anything extra that I need for the day job. A regular incognito window does all I need for testing, with the UX chrome in the expected places. Note I also have the indispensable 'Hover Zoom' and 'Vim bindings'.
I really, really, really want to like Firebug/Firefox but it's just impossible for me. I already tried to switch 2 times this year. Once with the FFDev and once with v36 (stable) - both times I was left just as disappointed. I open the developer tools and refresh a SharePoint page and the browser hangs for close to 1 minute - this is just unacceptable. Even IE doesn't have this hiccups. I know this isn't common and is only reproducible on v36 for me but it's a huge PIA. Other than this, I'm curious why do you say the chrome developer tools are inferior? I haven't used firebug in a while but AFAIK Chrome Dev Tools has most of it's features and since it's "native" it's smother and faster.
