What is the difference between the Faber Castell and Steadler line of fountain pens ?

[lowks]

I got myself the FC Emotion fountain pens based on recommendations by SBREBROWN. I love them. The thing is when I look at the Steadler line of fountain pens, they look good (with quite a price hike too), I am wondering what is the difference in terms of quality or usage for fountain pens from both sides. Can anyone who own or used both of them before chime in ?

Thanks.
