Who does MacKenzie look like?

I frequently get told that MacKenzie looks just like me.  While there are definitely some similar features, I'm not sure she looks "just like" me.  So I decided to pull out some pictures of me at the same age and do a comparison. 

I have always said that MacKenzie favors my brother Jeff.  So, I also decided to compare pictures of them at the same age...

So, who do you think she looks like?
