TubeBuddy vs. vidIQ

As the above two tools have many common features, so I am unable decide which one to use and for what. I request the experienced YouTubers to please advise:

Which of the above two tools you are using & for WHAT purpose?

Like I have installed TubeBuddy and I plan to use it for selecting keywords & tags.
I prefer TubbeBuddy, but it's all the same but the forums at Tubebuddy are better and more members have more interaction but this is my personal opinion, also the features of Tubebuddy I prefer and I recommend using Tubebuddy.
I use both but for different things and only the free versions.
