I always buy the H&R Block software since it is so simple to sue and accurate.. never had any rejections or questions from State or Federal taxation agencies.
Pros: Easy to install, Easy to fix issues, Easy to prepare, Maximizes refund, Fast
H&R Block mails me the software every year. It's an easy installation and very easy to input your tax data. This year they included a USB device as well! H&R Block is phenomenal software at a reasonable price. A must for the tax season!
