Sorry, folks... 
not in my opinion--
Yet like they say, that's why... 
they have horse races--
For my-two bits, "Spectre of the Gun" was a dog. I liked the sets but for my money, the writing was not up to Gene Coon's par.
And using a memory from Kirk (& Spock) comes about again in the "The Savage Curtain" which had I made the list "The Bottom Feeder Five," it would have been #5.
BTW, yeah, tumblindice, a 'Flying Lincoln' was an indicator of things to come.
