Cfs On Tapatalk

I have the 1st tapatalk on iPhone. I see they have a tapatalk 2 for iPhone too. 1 works fine for me, anyways have 2? Any reason I should buy that one instead?
The goal is to have an updated version, with less bugs and more ease to use. I had the version 2 and thought it was not well made, hard to use. Version 4 is really good.
