What better?

Has a new subscriber to TML, I have the following initial questions:

1) Which one of the Traveller rules sets is the best in term of playability?
2) Do people enjoy playing in space (ie from world to world) vs.  on a
single world?

Please e-mail me at [email removed].  I am just trying to a get a feel
for what basis of opinions people are posting.  Thanks.
