(Thanks for your kind words.)

http://hakank.org/common_cp_models/ is a page which collects models that solve the same problem in different CP systems (and mostly with the same approach). It can be used to compare similarities and differences between systems, though one have to do the comparison oneself.

A long time ago (in 2012) I did a talk on comparing features in different CP systems mostly focused how "easy" - subjectively and IMHO - it was to learn the systems: http://hakank.org/constraint_programming/sweconsnet_talk_201...
