Loved TNG. It was my first Star Trek series and I remember watching the pilot when it first aired. My childhood could get past the ropey season 1. It had some tremendous episodes and I still punch the air when Data does something awesome. Chain of Command, Best of Both Worlds, Inner Light, Remember Me, Pegasus, Face of the Enemy and plenty more.
However DS9 just surpassed it for me. For a show labelled as static, it's changing of the Trek universe was unreal. The characters, I mean compare Bashir of S1 to S7. Hell Nog got more character development than people like Troi! DS9 is my favourite novel and I will constantly revist it. TNG will never do that for me but I still love it.
