Yes, it is. Several years ago, Magento 2 was unstable with a lot of bugs and security issues but it has become better day by day. As a result, Magento 2 outweighs Magento 1 in all aspects from design (both frontend and backend), functionality, user experience, to the number of available themes and extensions. Apart from it, Magento officially announced the shut down of Magento 1 support in 2020, which contributes to increasing the motivation to migrate Magento 1 to 2 or develop a new site from scratch on Magento 2.
