the best and worse Course Books: teach&learn Vocab

[legokockica]

Hello
I would like to know which text book is the best/worst for you, as a teacher of English, for learning and teaching vocabulary?
What are the reasons for your choice?

Thanks

Best for business English would probably be The New Market Leader. it is a good book, well structured.
