Turbo - Tax advertise more than any tax software or tax filing services like H & R Block.  If it is a simple tax filing most tax software are free to Federal e-file.
In the beginning I found Turbo-Tax more consumers friendly and easy to use but it’s price is going up and up but people still paying because you data is there and makes easy to returning customer, Many customers do not like changes and keep paying more than other tax software.
As bittertruth said,  pay only 14.95 , Tax - Act  is getting better and not much different than TurboTax. The different is Tax-Act does not advertise as Turbo does.
If you are trying to save money on filing tax, you can use state tax on State Revenue Web site  which is free and file Federal Tax free using Tax Act.
