Best keyword tool.

[JayManOurMusicBox]

I've just started looking into keywords and therefore searching for keyword tools.
What are the best ones out there?
Anyone know if creatorstats is any good?
They ask for all my YouTube login details and permission to manage etc. Is it ok to give those information?

I've been using Tube buddy and VidIQ they've both got a good keyword explorer

TubeBuddy or VidIQ is what everyone will say if they use anything...like 99/100 times.[DOUBLEPOST=1456545026,1456544968][/DOUBLEPOST]Oh yeah, and I wrote a guide if you looked at the guide section that has LOADs of topics covering this:
