Magento 2 is not the mirror of Magento 1. Magento rolled out numerous drastic updates with its newer version 2.x.

Someone has quoted it very well,
“Magento 1 is the context and Magento 2 is the story.”

Below visual from MageMonkey is talking about the technical differences between Magento 1 and Magento 2.

Have a look,

Our Verdict

Magento 2.X comes with an improved functionality and over 350+ extensions so we recommend our E-commerce and multi-channel retailer to migrate to the latest version for better performance. If have an enthusiastic team of 1-3 employees and if you can uphold $2 million or up then Magento 2 is the best solution and if you are already on Magento 1.0 then it’s high time to migrate to Magento 2 without a doubt within the next 18 months as Magento has officially stated that they will continue to support older versions for an additional 3 years. Magento 2 provides features of scalability along with security and maintenance hence it is a great option for SMBs who are looking forward to taking the next step in the Magento ecosystem.
