I m really struggling with virtual box and Ubuntu, is it good for me switch into Linux os rather than window

Yes, Virtual machine eat up a huge chunk of RAM, therefore MS Windows work more slow. As mentioned above do not use Windows 10, 9, 8 and 7 with a telemetry updates. Of course, you should install the latest version of Ubuntu on your computer.

In any case beware of malware. Nowadays the large number of viruses are created for this famous build of Linux. They steal the private keys of crypto-currencies, transfer them to their hive and even encrypt the files on the disks. You need to administrate the user rights policy correctly.
