Not really. I've told countless people about how Opera really is the best browser, by far, and how people using Chrome and Firefox are stuck in the stone-age of Internet Explorer 6. I'm getting tired to repeat it.
Screw it, I'll do a quick run. Depending on how good your computer is, Chrome will buckle (freeze your computer, in my case) sooner or later after you keep increasing the number of tabs, due to the one process per tab design flaw. That does not usually happen with Opera (unless you have some very demanding pages, which doesn't usually happen to me), it will keep going as long as you have the RAM to supply it. Right now opera:cpu shows me a round number of 115 tabs with 1.5 GB RAM usage, plus the plugin wrapper grabbing an additional 400 megs. Given that this particular computer has 12 GB of RAM I think it's very reasonable.
Of course, I don't have a rocket computer at home but the performance is very good as well on a mediocre laptop.
Now, what good does it do to have 115 tabs if you can't see them or switch between them at your wish? In Chrome you have one line of tabs that keep pushing against another, and at 115 tabs you could not select your tab properly, nevermind reading the tab title.
In Opera I just configured my tab bar to wrap to multiple lines and aligned it vertically on the left side. I also have tab groups that work very nicely to minimize unnecessary clutter.
I can also turn the tab bar off altogether and move between tabs with ctrl + tab or right mouse button + wheel, or hold ctrl + tab + mouse click.
The possibilities for customization are so numerous I can't be bothered to describe them all. Opera is a true browser and it has all these features out of the box without getting in your way.
You're a hacker? Where's your curiosity? Explore Opera's features (like mouse gestures, keyboard navigation, and so on) and see for yourself.
And by the way, one last thing. The default option for Opera is to restore your tabs from your last browsing session, which was not the case for Chrome and Firefox last time I checked (and if that didn't change it's retarded, although I would understand the reasoning, they don't want to encourage you to keep your tabs open because the browser might buckle under the pressure of 10 open tabs). So really, feel free to keep open as many tabs as you like.
You can also use ghostery (an extension) to block all these resource-consuming background scripts, just in case you have reached the limits of your hardware.
I have enable 'plugins only on demand', so no Flash player will be loaded without my explicit consent. Again, this is out of the box. Also, content blocker. And so on and so forth.
