Device Simulator and ignition

Hi All,
We started using ignition dairy demo simulator for our work. We installed WebDev module to ignition and added all the tags required for our simulator. We found WebDev module looks more promising as it exposes REST API’s to control all ignition resources using code.

Would like to know fro the community if there are any pros and cons of ‘dairy demo simulator’/ Webdev module before we move forward.
