The ES (2022) is a long vehicle, longer than the NX. Its has superior ride comfort to the IS, NX and at times, on certain terrains even the RX due to its low centre of gravity.
Be careful though, and make sure you've taken it out for a test drive prior to purchase. Visibility out of the car was a huge issue for me compared to my RX. I agree with Derant, the turning circle is an issue, primarily due to the car's sheer length, similar to my RX.
Also, it's a low car, as low as my coupe that I use for weekend racing. It can feel claustrophobic on gloomy days. Driving in central London is challenging due to its length, low height and (comparatively) limited visibility.
NX and RX are a different category of cars to the ES and IS. I would strongly recommend driving an NX or RX prior to deciding on a saloon car.
