I am not here to judge, but, I am asking about what features Opera browser have, but other browsers doesn’t have it?
Speed Dial, sidebar, and generally just looks much nicer than chrome. Although tbh, you’re better off using Vivaldi these days for that stuff
It’s a good browser. A nice social sidebar, auto pip YouTube, video enchanter, GPT at sidebar, handy music player, going to support local llms
I don’t use it because I want to sync everything with my phone and Opera mobile’s tab handling is not my taste.
I am currently using Opera as my main browser for work purposes. I know Vivaldi has better customization but with Vivaldi my PC’s fan goes crazy as if it’s a Helicopter.
I find opera a great browser for desktop (windows and Mac), it’s not so great for Linux and it’s awful for iOS and has to be refreshed.
Opera has Workspaces (I think it was the first browser to implement them), it has a sidebar with Messengers, a music player and Opera flow that connects your phone to the desktop browser.
Why not to use Opera? Well if you care about syncing your phone to the browser and use iPhone you won’t be able to sync nothing as the feature is not available on the iOS app. If you use Linux Opera tends to be a bit slower than other browsers.
I used it from 2004 to 2012 because of the features offered. After the release of Opera 12, Opera Software sold off their company and the browser was left to rot. I have moved on to Vivaldi which is close to the original Opera.
Used to use it but found out that Edge can do everything Opera and OperaGX can and so much more things.
I hate new look of opera. I prefer edge.
I don’t use it, but it is a pretty solid one. Lots of useful features, fast, IMHO the best UI among other browsers . But I don’t like the fact they don’t allow me to choose. I was disappointed when I wasn’t able to set my custom home page. Opera just didn’t allow me to do it. This is the only browser that behaves like that
I can’t drag lots of tabs from one screen to another, only one tab. I mean I can’t choose 5 opened tabs and drag them with one click. I have no idea what’s the reason of that, but it is very inconvenient and strange
I use Edge but I was using Opera untill I discovered Edge is the best one. Opera is the 2nd
I just wanted to try out the build in a.i, tool, but it’s still on my system, and I actually sometimes use it. The build in a.i. is rather underwhelming 
Actually I could not tell you what’s good about it. It’s just another Chromium clone.
I used to use it fast and simple but since they changed the gui i didn’t like it anymore. Also it started to consume more memory and ram and sadly i don’t have a good computer so now I’m with edge
I don’t use Opera but in my opinion it has the most modern and polished ui out there.
only reason is the sidebar, and there is no alternative that works so well
Speed is what it have.
because my family has used this browser since I was born and still does, so I continue this tradition? the browser seems to be good, but there are advertisements and functions that I don’t need, like AI, and it’s not a problem for me to configure it; removing unnecessary functions is the first thing a user of any browser does; all browsers need to be configured, starting with edge, which is used to download a normal browser, ending with firefox + I like the VPN function and you can set up a dns server, I personally use cloudfare and redirect to HTTPS forcing sites to work on it
Fast.
Speed Dial.
Pretty.
Opera is chinese. Not safe
i used to use it. its great simple and looks good imo. BUT ram avrging 1000. so i switched to Vivaldi which is good but little more complicated. then switched back to edge. edge is everything u need
Looks good, has good Tools, good customization, VPN and adblock integrated, cpu/ram limiter is actually helpful sometimes…
There’s a Lotta good in there.
No longer use it, but switched from it a few years ago. I liked it because of the sidebar, the integrated RSS Reader (which looks the best if you choose the card/magazine view (whatever is it called)), the Speed Dial and all sorts of small things that you do not need an extension for, compared to other browsers (e.g. the pop-up when selecting text etc.)
I now switched to Firefox, because Opera is less friendly with older versions of Debian than it.
