Sonata model, in general, is really nice.
Exterior as well as interior design are probably one of the best out there for the sedans.
SE has a bit more aesthetic aspects than the GLS (chrome grills, door handles, dual exhausts, tire, etc).
The comfort level of SE is sub par.
Noise level during the ride is also quite annoying.
These are due to the sporty suspension and less-cushion tires, but they shouldn't be the excuses for these crucial aspects of the car.
If you can live up with this, it's an amazing car.
If you think you and your family rather like a quieter and comfortable car, go with GLS or Limited.
I thought the SE wouldn't have much of a difference, but it really does.
Exterior and Interior Aesthetics
Save so much on gas!
Comfort (big time)
Noise level during drive
These are the only negatives, but they really need to improve on these.
I can't imagine driving SE for more than 2 hours without taking a break.
(Noise level is to the point that I have to increase the volume of the music significantly while driving than when I am not)
