TNG DS9 VOY era was simply the best and the most influencing.
You clearly have no idea what you're talking about. There's a reason people still talk about TOS nearly fifty years after its launch. The characters still resonate with people. That cannot be said about Modern Trek
I dunno if it's a British thing or whatever but people my age seem to be WAY more aware of TNG than TOS. Jean-Luc Picard is an icon, no doubt about it. When people my age think of Trek they definitely think of the TNG/DS9/VOY era first. It was everywhere!
People in this thread are acting like TNG was some obscure cult show but it's actually one of the most famous TV shows ever aired. By any measure it was more successful than TOS. A genuine pop culture phenomena when it aired and still widely beloved today. Among young folk, TOS is thought of as the goofy predecessor to real Trek.
