I've been using H&R Block Deluxe for several years. Before, I used the other one. This one's easier to use, is a great value, and the user interface is easy to navigate. Improves every year. Gets both my taxes and my neighbor's done in a snap, and she has some pretty gnarly investment transactions. I would definitely recommend it. Love, love, love it.
Reasonably easy to use if you answer the questions and go straight through. More problematic if you need to go back and redo/add/subtract. Overall quite happy and I think a good value.
