It seems to serve the same function. It has an issue where you often have to restart to connect to the online community and will end up disconnecting every hour or so. I would say stick with Origin for as long as possible. There are way fewer issues. The EA client also has more ads before you can find your game making it harder to access. It will automatically bring up the last played game which can be helpful. I can't figure out how to put it in light mode or get a desktop shortcut for starting up the Sims.
