I've been a Quicken Classic for Mac user for years and just started to also use Simplifi over the past year. Quicken Classic is a great app! But, the problem is it is desktop only. There is a mobile app, but I can only download transactions/balances from the desktop, then they will sync to the mobile app. Simplifi improves on this by storing its data in the cloud, so I can see up-to-date data on any device. However, the web app doesn't even come close to the polish of Quicken Classic for Mac, and as a web app, I don't think it ever will.
We need a native Mac app to make Simplifi truly great!
