My opinion, they both have their ups and downs. Overall I equally like them in the end. They have really stepped up their game and make some nice cars now. I've been comparing these along with the fusion and malibu when I get them as rentals for the last couple years now as possible new cars for my wife to replace her Mazda 6. All the ones I've driven were 4cyl. Heres my thoughts on them.

Optima: better exterior, interior feels dated, rear seats uncomfortable, drove really nice.
Sonata: decent exterior, much nicer/modern interior, heavy gas pedal makes accelerating from a stop kind of lurchy.


My personal favorite all around so far has been the Malibu, for whatever its worth. Doesn't stand out in any one category, but overall I like it as a whole more than the others.
