The really simplest answer is that LOGO is a superset. You can do all
the things that Karel can do and some very important ones that the
standard Karel can't (such as help the children learn the calculus of
differential geometry of vectors). There are many further reasons,
including that most LOGO systems allow multiple interacting turtles
and this allows a look into particle systems ....
For children up to the age of 12 or so, we think that the Squeak
etoys are better than either because there is a much closer match to
real power and what the children can hold in their heads. Children of
this age tend to do bigger and much more interesting projects mostly
instigated by themselves in etoys ....
Cheers,
Alan
