"Lego has outdone themselves with this set. There are substantial upgrades over the EV3 set. - All components are smaller and lighter - more space to build, and less weight to carry. - Fast startup. - Four motors included, absolute encoders built in. - 6 axis gyroscope built into hub. - 5x5 led can scroll text, show animations, etc. viewable from a distance. Program expressions for your bot! - Rechargeable lithium ion battery included. - Scratch language is intuitive and powerful. You have advanced functions like trig if you want them, and can make custom blocks. Works great on iPad. - Python built in - no need for alternate OS. - More parts included - I prefer the wheels and find the parts more convenient to build with compared to the EV3 set. Also more gender neutral. Remote control with game controllers (PS4, XBox One) built into app.
Side/downgrades - 6 ports on hub that can be used for motors or sensors. 2 less than EV3 but more versatile. - No SD slot - less opportunity for future upgrades (they got custom Linux builds on the EV3 brick). - No built in debugging or remote control on the hub. You need the app and a program (5x5 display does not allow for a menu system) Overall would recommend! My boys and I have been having a blast with this and the EV3 set."
