I didn't fall off the turnip wagon yesterday.

But from browsing these forums, so far it seems to me that most of the "strong feelings" are about the setting changes--the rebellion, the new era, etc--not the rule mechanics. Even for T4, I haven't seen any criticisms of the rules themselves, just the frequent typos and layout problems.
Let me put it another way:
Which edition creates the most characterful and interesting PCs?
Which edition has the best starship/vehicle construction rules?
Which edition has the best combat system?
Which edition has the best task resolution?
I'm already familiar with GURPS and D20, so it's the unique rulesets I'd like to know more about--CT, TNE, T4, Mongoose.
