Personally, the Lego stuff was unreliable and a lot of time was spent by kids in making sure the robot worked across different conditions and there was a lot of pressure on them on ideal placement etc. Again, great things to learn for kids but very frustrating as this is the first foray for elementary kids into programming/robotics.
FTC in comparison has been way more fulfilling for my children and I am hoping the next version of FLL is a lighter version of something similar.
