I will caution that while fighters in small numbers have low survivability (the mention of "average survival of two minutes and twenty seconds" in someone's fighter description comes to mind), large squadrons of fighters can be devastating against even picket frigates. Once fighters manage to surround and approach from all angles, shields are irrelevant -- even 360-degree shields, since fighters will simply pass over them to shoot from within the shield bubble. (Of course, this requires a fleet point cost well in excess of the fleet point cost of the frigate, meaning that it's simple outnumbering with a superior force and not anything inherently successful about the fighter.)
All told, however, I do think that fast fighters are far more enjoyable. The 200-range of speed should be the general norm of a fighter in my opinion.
Personally I want to have some Wing-Commandery gameplay with controllable fighters, even if only for missions, and the first mod I make (whenever I get around to it and once I figure out where my cognitive dissonance is in failing to get Eclipse working) is going to focus on that. I think fighters are overlooked because they have such low survivability and because the gameplay tries to capture that Star Trek feel, but the Federation fighters mentioned in the dev blog were always my favourite parts of DS9 (and TNG, for the Maquis fighters). =)
