Help me choose a car!

We are turning in our lease on our 2022 tucson. The wife drives the car the majority of the time because I have a work vehicle. We put on 28k miles in 3 years so we don't drive a whole lot.... wife "doesn't care" what we get. We test drove a 2025 n line sonata and an Elantra N. I fell in love with the elantra because, well, I'm still a kid at heart. She said she couldn't tell the difference. We have two kids under 7 so there will be two car seats in the back. Am i an idiot if I buy the elantra n over the sonata? They are both like 37k. Also debating leasing over buying because we don't drive a lot of miles and enjoy having a new car. Inputs?
