Tubo tax is my favorite. It is much better than the US version, although the US version has been watering down the user experience, and I switched to Simple Tax a few years ago. SimpleTax is almost free (donation) and although not quite a nice to use, I like free or under $20.
What I miss a lot about Turbo tax is the way that you can enter in $'s on the form (TD1) and double click to toggle between their questionaire format, Govern't form format, and the specific detailed calculation schedule forms. It is very hard in comparison to do that with Simple tax - I am endlessly scrolling through their questionaire format to get to look at the Govt forms and I can't enter directly there.
I do miss the fast, simple data entry options of Turbo Tax. (when you are familiar with the forms, anyway).
