Interchange or Top Notch?

[Donbelid]

Hello everyone.

Which book do you prefer?

1. Top Notch (Pearson - Longman)
2. Interchange 3rd Edition (Cambridge)

Could you please explain why or clarify on positive and negative points of each book?

Everyone's idea is needed.

Thanks in advance.

I've taught New Interchange and then Interchange 3rd edition for quite a few years. It seems a perfect text book for learners of English as a foreign language.

But recently considerable excitement has grown among Iranian language institutes in favor of the new material--Top Notch.

Top Notch seems better as far as vocabulary, luxury and surface attraction is concerned. In other areas (sub-skills and skills), they seem to function the same.

I need teachers' advice & opinion.
