You have to be careful. You are right that KiCS2 is generally faster,
but this depends on the kind of applications. It is much faster for
purely deterministic computations, but for non-deterministic computations
it might not be the case. Since KiCS2 offer much more flexible
evaluation strategies, this comes with some cost. There are cases
where non-determinism is duplicated (due to the combination of laziness
and non-determinism) so that you might get an exponential increase
in some computations. See
http://drops.dagstuhl.de/opus/volltexte/2012/3616/
for a discussion (and partial solution).
Best regards,
Michael
