This is much much better than Conan

The closest detective manga I can relate Q.E.D to is Conan and Q.E.D may have some similar concepts to Conan but in Q.E.D the stories are more thoughtful, the characters have more depth, the annoying plot in Conan which detached itself mostly from the cases is nowhere to be found etc. I could go on and on.

I'll hold back on saying this is the best mystery manga I've ever read, because it's not. But it is a good mystery manga, and I do hold some respect for it. I never get into this genre.

I've only read the first volume. The cases are certainly interesting, and I really like the characters. BUT the killers rely far too much on an incredible amount of coincidence and on everyone doing the right thing at the right time, stuff they could never have predicted. It's not believeable at all! I hope it gets better as the author gets a better grip on what he's doing.

Mediocre manga

Man I remember reading this series way long ago. Almost forgot about it. I'd say that the plot is quite mediocre. The mystery itself is not that interesting. Touma is a genius who graduated from M.I.T. His ability of deduction allows him to solve the case easily but I feel something wrong within his characteristic. He seems lonely in some point. I read through vol.9 and there was no almost character development at all. I'm pretty sure this series will make you sleepy enough if you're not patient to wait for something interesting to happen.

The perfect shounen mystery series

I like Detective Conan, but I love Q.E.D. I love that the author has clearly actually been to (or at least researched) foreign countries and draws sympathetic non-Japanese characters, including non-white ones. The main characters seem like real people (a rarity for mystery manga), and the cases are varied and complex. I like the level of scientific detail included, though it can be a little hard to read if your Japanese isn't so good.
