Magento 2.X is the initial version with major changes from 1.9.x. Its used composer and many latest headaches to install and update it. To install Magento 1.9.X or previous version you no need to have much experience and you can install it in a couple of hours. But Magento 2.X is very difficult to install on shared servers. I tried this and successfully installed it in shared server, but with a lot of time and efforts. WE need to have much knowledge on command line PHP and composer options. But I don’t recommend it if you are not very much technical. It would better to go with Magento 1.9.X instead of taking the burden to install and execute this version. After installation also there are many changes that need to be done from a command prompt.
But look and feel is very good.
