I have worked with Artisteer for the last few years, and even after using TT for only 1 day, I am so impressed that Artisteer is completely outranked.
Support here at TT is incredibly fast and helpful, where in Artisteer I sometimes waited for weeks to get an answer. Artisteer support copies and pastes their answers from other posts, without actually looking at your questions.
The few minor glitches I found in TT were solved within 24 hours.
On top of all that, Artisteer has in all their wisdom decided to remove the Visual Editor from WordPress when uploading one of their themes. Now that is what I call 'messing with code to cover up messing with code'.
Extremely bad, especially when you are building themes for clients to use. How am I going to explain to them that when they want to change anything on an existing page, they have to learn HTML??? They pay me so they don't have to understand code.
Add to that the lack of extra page templates, and I think my choice is well made. Needless to say, David, I couldn't agree with you more.
