I have been using HR Block (TaxCut) for 10+ years. My only suggestion would be to make navigation through the review process easier. It is sometimes difficult to find certain areas of a return.
i ran into a problem with a partnership agreement, the acct doing it had put figures in 3 columns and you program told me i had to contact your pros, i tried and was told the only way it would work was with the online version, as i was almost done i declined and just added the figures together as you would have to go with me and explain the problem if i got audited. other than that i have used the program for years and it works pretty well.
