I had not tried UC browser before but now talkers am I impressed!
Data eating- UC consumes less data compared to Chrome(even with its 50% compression)
Media upload- UC uploads images faster than Chrome and goes further to show upload progress, in terms of size of upload.
Saving pages- UC has ability to store pages for later reference while Chrome still misses the feature.
Add-ons- UC has rudimentary add-ons such as Ad blocker but Chrome doesn’t.
Aesthetics- UC has customizable themes, backgrounds while Chrome doesn’t.
Size- UC occupies less storage compared to Chrome(almost double)
RAM hogging- Chrome uses much RAM compared to UC browser.
Speed- UC is snappy compared to Chrome.
Download manager- UC browser has its downloads window from where you can manage downloads while on the other hand Chrome uses the android downloads app which isn’t appealing in showing progress of downloads.
