It's not only my opinion - that's the whole point. Leading lights in the recording industry rely on ATC - their reputations for producing good recordings depend on them.
I've never attacked PMC, but people who have heard them turn their noses up at the exaggerated bass from the transmission line. Probably impressive over a short demo, but this is exactly why you need to live with speakers for a while - to get a handle on what they can do. You are currently handle-less, hence the erroneous beliefs you have.
