You're right. SNW has done a lot more with Uhura and she's been great. Same with Chapel. Jess Bush is outstanding and helped create a much better character than the one Majel was saddled with. But it's not a fair comparison.
In the original series, Uhura and Chapel were supporting characters. Nichelle was a day player, Majel was simply recurring. It wasn't a series about them. It was about Kirk, then Kirk and Spock and then finally Kirk, Spock and McCoy. It was a lead-driven series with plot-driven stories as per the standards of the day. There was minimal character development because that's how TV worked then. SNW is an ensemble series which will be plot or character based, depending on the script and the characters will grow and develop over time. As per modern standards.
That doesn't make the original series any less great, just a product of its time. Whichever you like better is a matter of taste. As for the original series being a "pinnacle" - well no follow up Trek series has entertained me as much, as well and so consistently. No new Star Trek series will every top it for me. But everyone has a favorite. You don't like arguing with fans? Then don't. You won't change an opinion of a fan who has been devoted to a TV series for decades.
