Thank you Aramis erak, for adding details on the use of the dice for each of his editions of the Star Trek role-playing game.
But what is the best for you to play?
None of the above. I wrote a ruleset back in the early 90's that works far better for me, but it's never been "finished" - it was based upon hybridizing T2K 2.0 and FASA Trek... but with a different skill resolution mechanic than all of the above. It is, however, what taught me that Xd6 vs Skill is essentially a poor mechanic...
FASA and LUG both are preferable to DTrek; PD1 is preferable to FASA and LUG for certain types of campaign. GURPS didn't work well at all; Star Hero was too much work
Starships and Spacemen is a Trek-knock-off, but it's better as it's own thing, not as trek.
