My first SCX vs my first Scalextric

Here you can see how different these two companies are trying to reach the youngest slotters. While SCX (Spanish Scalextric) has made the set at you left for kids from two years old, Scalextric (Superslot in Spain) is selling the one at the bottom for children three and older. As you can see the spanish SCX is RC and very easy to set up. It comes in a box you can use as a playmat after using the toy. The Scalextric one is just a HO or 1 64 set. Which one you think would better fit with your kids...
