Dora is better in many ways, just like in real life but i don't care. 109 is my favourite bird and always will be. I just love the cockpit, it feels like home to me. Ergonomics doesen't really matter so much in sims than they did irl and 109 gauges are well organized, very easy to check all important gauges between dogfight. And no one climbs like it.
I don't agree about poor weapons, while 30mm needs some fine tuning i found it be much more effective than dora's 20mm's.
And looks wise 109 wins hands down, no question about it. :D
