Original StarTrek series and Next Generation were the best StarTrek series. Gene Roddenberry was a great visionary, and many of his concepts came true. Since that, there were a number of attempts to revive the franchise, but none came close and likely will never will.

Finally, the later series leveraged better technology and graphics to compensate for Gene’s lack of his visionary thinking.

Also introduced idea that Gene influenced other writers to follow his foot steps and create great Star Trek series. I'd like to address these points.
1) Roddenberry's shows were not as popular as newer shows that were made without him and mostly without his influence. Acdording to two sources Voyager and TNG were more popular than TOS.

2) yes, we couldn't have startrek spinoff without Gene Roddenberry, but that wasn't the debate. The debate is if we can make great Star Trek series without him. His inspiration stays on, but more popular shows were made since without him.

The inspiration of Star Trek was important as stated by @CYDdharta
I certainly have respect for his legacy, but he created something bigger than himself and other writers created even more popular series based on that insipiration.

and @agsr, you both made great arguments, pivoting your debate on the fact that Original series was visionary for it's time and spawned of other ideas. However, that still doesn't address the point that subsequent series were more popular than the orginal while made without Roddenberry. An objective measure of how good a series is based on popularity, and multiple sources were provided to demonstrate popularity of the various series.
Great debating with you, and since it's final round, I look forward to the votes.

The very latest episode of the current TV show will normally get more hits than an older episode.
Better should be measured by how much impact it made on the society and forward. TOS did that. It created generations of fans, spin offs, and prototypes of future techology that wasn't even concievable at that time.
In conclusion, I attribute all of that to the StarTrek creator, Gene Roddenberry, who both created the show, and inspired future generations of writers, innovators, and fans.
