What is your favourite bilingual dictionary? Why?

Hey! I always use the Cambridge Dictionary and Google Translate for German-English/Spanish, but I know there are many more options out there. So I would like to know which one is your favourite and why do you use it. 

-- Is it because it is reliable?

-- Because it is straightforward? 

-- Because it is easy to use? 

Should I change to another one? What do you think?

(And I do know Google Translate is not really the most reliable option and neither a dictionary, but it is very convenient when it comes to translation)

For me, it depends on the language. Overall, nothing beats Google though.

As I work as a freelance translator, my clients don't like me using google translation, but personally, this is the best of all. 

This has been very interesting so far because I didn't expect people preferring Google Translate over dictionaries.

I guess it is just more convenient :)
