Frosty: I'd say the 84 is superior to the 38L, but it's a more even matchup against the G. Against either model, if you run into a pilot that knows how to use his flaps and when to be aggressive, you've got a great fight.
Edit: Disagree about the 84 = Spit comment. While you CAN fly the 84 like most people fly a Spit, being successful in the 84 requires a skillset that many Spit pilots never find a need to develop.
