Positives: Better headlight than 2G "S" model, a hair more power when stock (but we're only talking 1-2hp), no "oil burning" issues.
Negatives: Weaker front brakes, slightly softer suspension, slightly slower steering geometry, 0.3 gallon smaller tank.
There's over 100 differences between the two, most are trivial and other than what's been mentioned above, I wouldn't really put them in positive/negative categories.
