If you want me to make a comparison, I hope more about the continuation of Tantei Gakuen Q than the Kindaichi series.
I have already bought 22 of the licensed volume in my country. Quite satisfied with the storyline, type of case, drama, and how they solve the case.
It was really fun to see DDS than Kindaichi. But, Kindaichi seems to be much more popular so that there are more sequels and spin-offs endlessly.
No wonder about the end, they become successors of Dan and each one gets a piece. The goal is clear so it is difficult to continue.
Every time I look at Kindaichi, maybe it's what it feels like to see Shinichi if he didn't experience the incidence of his body getting smaller due to drugs.
What's interesting about Kindaichi is only the type of case faced.
Detective Conan is still great in terms of practice and analysis taken from in-depth research in the real world.
It is repetitive and there is no major development, but I keep reading this series.
