According to the banner notification on my Mint screen, Credit Karma will have all the same features I use in Mint: Net worth tracker, transaction tracker with categories, trending, budgets, full history, etc.
I will probably just transition over to CK, because it appears to be mostly a branding change.
My understanding though, is that if I don't like CK I'll lose the option to move my data from Mint to one of the other services mentioned here, because my Mint access will be lost. Is that a valid assumption, or is moving just as easy from CK as it is from Mint?
