What are the differences between the 'teach yourself' and the 'living language' series

I found pretty good reviews about the TY on the web, but hardly could find any about the livinglanguage.

What are differences between them?
All I know is that both come with audio and both teach grammar also.

thanks

Here is the link to a video where Robert makes a review about some series and specifically about the livinglanguage:

These are obviously popular courses because I just read another positive review on the blog posted by user landho:
