All of winsis cat information verified and then input by a handful of people, i would generally consider it to be more likely to be correct. all German shows are listed, but only national level shows from other countries. and then only the classes that are seen at the german shows - 12 months and older. Like to see the list of progeny, showing titles along with hip/elbow ratings. breed survey reports and also show critiques are listed for most dogs.
pedigree database is easier to advantage and more photos are available. i like the reverse line breeding option.
working dog eu, i don't use as much, but it is a user based input system also.
i use all 3.
