I just did a quick comparison for my personal use between these browsers and the only few things I considered were:
- Performance: How smoothly the window resizes and the browser updates the layout.
- Memory consumption.
- CPU power
- The latest version of all 6 browsers have been used
- All of them have 3 tabs on the same websites open (AppStore, Microsoft, YouTube)
- The comparison has been on MacBook Pro (15-inch, 2017)
- It’s not a through test just enough for me to see which one suits me
Here is the results.
- In terms of performance Safari, Opera and Firefox are the best. The other 3 are laggy when resizing
It’a hard to tell which one is more efficient immediately as they all have side processes running but seems like Opera consumes least memory and Firefox uses the most.
Tracking CPU is even harder than memory but Firefox is always on top consuming the most CPU time and Safari is the most efficient one. Edge, Chrome and Brave are pretty much the same.
The Winner on Mac is Safari but it’s not a cross platform browser. The next Winner in terms of performance is Opera and then Firefox. Chrome, Brave, and Edge failed the first test so they are not even considered as options.
I used Opera for a week and it has these cons:
- It has issue with location and google map couldn’t show my location OK.
- It doesn’t have a good support and not listed as the supported browser for some websites.
- Due to the limited support for import and export, it’s hard to switch from other browsers to Opera or switching back to them.
- It doesn’t allow sending feedback.
- The settings page is not well organized and it’s not easy to find the settings you need.
So switching to Firefox now.
