I've used H&R Block Deluxe since it came on the market. It's interface and format are user friendly -- I just answer the questions it poses. Updates are downloaded as soon as they are available from the IRS and/or the state. Prior year data is imported into each new year. The five free efiles that come with it are a very welcome. I've never had an issue with this software.
Pretty easy to use and import data from previous year's return. Cost is not excessive. Would like a physical CD instead of just uploading from internet in case of computer crash. State filing should be free since most users do not utilize all 5 free federal filings.
Pros: Easy to prepare, Easy to import documents, Fast
It gets the job done. However, the navigation is quite cumbersome. It's hard to jump between topics. If I go back to one topic in the preparation process, it is hard to return to the place where I previously was without clicking through the "next" buttons several times. The steps / layout should be more graphical and interactive rather than on the top menu bar. We are in the 21 century where the user interface MUST be graphical, not text.
