Is there no specific reason why you like it better? Usually you can explain why certain software is preferable to similar software. For example, I use IntelliJ over VS Code for writing Scala because I've had difficulties getting the Ensime extensions to work properly and IntelliJ usually just works. I use VS Code over PyCharm for writing Python code because it's lighter weight and offers 99% of the features that I need. We use Slack at work instead of IRC because there are a lot of non-technical people who need to communicate with the dev team and Slack offers an easy to use UI for organizations.
