Well TC is much older than Bitcoin, so you'd think newer stuff by the same author would be better. But it's hard to say anything for certain. The projects are so different in form and function. TC targets Windows, Bitcoin targets Linux. (Yeah, they're cross platform, but if you look at them you'll see what I mean) The cryptography code included in both is public domain/third party so that doesn't help. Bitcoin has networking, TC doesn't. TC is a driver primarily, while Bitcoin is not. They don't use the same GUI toolkit. So a lot of it is really hard to compare because the style of the code is following the common idioms for the framework being targeted. Where the author is more free of convention, they don't feel similar to me.
