Credit Karma or Intuit TurboTax? Which is 'better'? Pros and cons of each?

What are the pros and cons of Intuit Turbo tax vs Credit Karma?

I expect, if the moderators even allow this question, something like this:

Pros:  Credit Karma is free, Intuit TurboTax is not

Cons:  CreditKarma is not comprehensive, has holes, not intuitive to use.

Pros:  using either Credit Karma or TurboTax cuts down on errors, makes it less likely you'll be audited (true?  Not sure)

Cons:  Credit Karma is online, and in theory a stranger can hack your personal details and find out how much money you are making, while TurboTax is a standalone software application that resides on your hard drive, less likely to be hacked online (not sure if this is true as Intuit might even be 100% online these days)

I'm making the above up, just to get the ball rolling.  I'll check back in one week to see if anybody answers.  Thank you.
