I much prefer the downloaded application over the website. I felt more comfortable browsing back and forth and verifying the documents. The web format felt more opaque. Furthermore, in previous years the Deluxe package was sufficient this year, with no changes in the complexity of my taxes I was forced to upgrade to Premium
More functionally is getting gated. You use something simple like showing you have losses they tax it. They don't just let you put it in yourself or even tell you you are about to pay for it until the end. Everything is too rigid where you can't directly affect the form.
