Been using TurboTax since it was Chipsoft Loyal customer a little disturbed by the eFile costs for state returns. Especially when I have several to file.
As a retired CPA I could do my tax return manually but I prefer TurboTax because it's easy to use and I know the math will be right. If I forget a deduction or credit, TurboTax will remind of it. It's a great product.
What's great about it: Easy to use
What's not so great: Delay in 2014 getting the sales tax calculation
