This debate is still ongoing?
Let me put an end to it, then

The 109 is the better "fighter"
The 190 is the better "killer"
They can each do both, but there's a subtle differentiation in the categories.
As for the Dora: It climbs like a 109, turns like a 190a5. It's acceleration is through the roof, and can loop, rolling scissors, yo-yo, at least 10 times better than an A-5 when furballing. The D9 is a much better furballer, since it won't reach that "oh crap I'm dead" moment as quickly as the A5 will.
I'd also be careful suggesting newbies start with the F-4. It's a nimble plane for sure, but as far as killers go, most newbies won't like it, may get frustrated and give up. The slow speed, inability to disengage, run away, or chase anybody down, will get on their nerves. The faster G-2 is a better option, but I'd just suggest flying the G-14 with 20mm hub gun to learn. Superb power, climb, accel, and same hub gun. It gives you the tools to be competitive in the LW environment but still learn the quirks and foibles of the plane type. Once you get a few kills and feel comfortable you'll be better suited to move on to the G2 or F4 models.
Just my thoughts on the matter. It's like the spit1. Best turning spit by far, but nobody wants to start in it because you can't kill in it without some modicum of skill. You get that skill on the higher marks (the more competitive ones) then work towards it.
