TapaTalk - Yes or No - Why?

So I see that DBT uses Tapatalk and would like to know the advantages of using it rather than the stock ForumRunner.
What are the disadvantages?
Why is it better than forumrunner?
Why is forumrunner better?
Why should I switch from forumrunner to tapatalk? Or, do I even have to switch, can I run both?

The majority of our developers already had Tapatalk installed from before FR got included with the stock package, it's as simple as that
