Quintura vs Google search question

[nativeaio]

hi guys, I have a question for you regarding the keyword research method that Vita has thought us.
I found this visual search engine at http://www.quintura.com wich seems very similar to the "old" wonderwheel that google killed. Now I tried to run a few keyword researches in both Google and Quintura to see if they gave me the same results as far as related terms, and as I was expecting they were very different.

Which one do you suggest to use as result?
1. Google because thats what we are aiming at ?
2. Quintura that seems to use Google anyway to work out its results?
I'm a bit confused cause I very much like Vita's system and would be great to be able to use it with this great visual tool.
Thanks a lot for your time
