I find that the rules play quite well. In fact I have a player in my game who normally has a very difficult time with game mechanics, he picked up the CODA rules in a short time and very much enjoys the game.
I can't really say whether they have a Star Trek feel because my campaign is set outside the Federation and is not Starfleet, so the games don't flow much like a Star Trek episode. However that is more a matter of the way the game is run than a mechanics issue.
On the other hand, I find the rules to be very adaptable. I like that because it means that rules from other games where I like the setting but not the rules(cough..D20..cough) can be easily converted.
I also use the excellent Cyberpunk 2020 rules from R. Talsorien Games to enhance the unarmed combat rules. I also make use of the cybernetics rules from Cyberpunk and have adapted the setting to the planet Tortuga. You could call it Cyberpunk 2376.

There are few problems in the galaxy which cannot be solved by a suitable application of concentrated phaser fire.
