2018 Lexus GX460 vs 2018 Lexus RX350/350L
 

I am trying to decide between these two cars. I currently have a 2015 Lexus GX460 on a lease. Has anyone gone from the GX to the RX, and if so, what are you complaints if any? How was cargo space utilization on long trips? How are the seats on long trips?

Thank you in advance for your time.
