Ubuntu is much more faster over Windows and helps to get software and other utilities easier and within a short span of time compared to Windows.

Ubuntu helps to get robustness and resiliency over Windows. Ubuntu runs faster than Windows on every computer that I have ever tested. LibreOffice (Ubuntu's default office suite) runs much faster than Microsoft Office on every computer that I have ever tested.

I liked manjaro a lot, the huge support it has and the variety of tools it provides is just awesome. But due to its parent platform being Arch Linux it has bleeding-edge technology and that meaning, we get updated 'daily', and if we keep updating the system daily, due to the bugs in the recent updates the system sometimes used to crash, this made the OS really unstable. However, one can avoid such crashes using periodical and careful system/package updates. I now use LinuxMint which is based on Ubuntu, and this OS is completely stable with reliable(mostly tested) updates. And, since this OS is backed up by UBUNTU the concerns/questions one can encounter while using the OS can be easily rectified using the UBUNTU community, which is pretty good. Though this is backed up on UBUNTU it most certainly does NOT include the proprietary stuff of UBUNTU, which is on the bright side of the OS. That's it! Happy Computing.
