Oh I quite agree, 5 and 6 were both excellent but the story arcs were problematic and the non-Moffat episodes, Neil Gaiman aside, often weren't the best. I've always found the RTD era more consistent in general, all of it felt like it was written in his voice and overall felt more polished whereas the Moffat era was fairly hit and miss. He certainly has creativity in spades but having to manage an entire series saw that creativity pretty stretched thin. It just wasn't a job well suited to him, ultimately.
