I'm sure that other, more experienced voices will chime in, but my two cents.
I can't speak to the Faber Castell or the Delta, as I have no experience with either.
One of the first pens I got was an Urban premium. There wasn't anything wrong with it, but I only used it a few times-- it felt weird in my hand and I had other pens I liked a lot better. I don't post, but the size of the cap would seem to me to make it kind of back heavy if you did. YMMV, of course. It is currently slated to get sold/ PIF'd/ something, because I won't use it again.
I recently got a Studio, and love it. It is the first fountain pen I've yet encountered that lets me write like I feel a FP is supposed to-- the nib is smooth, has good flow, and I can hold the pen comfortably for extended periods without noticing I've resorted to the "ballpoint death grip"/ actually write just using the weight of the pen. Some people have commented that they find the metal section slippery, don't like the fingerprints on it, etc, but those don't bother me. I also like that the nibs are easily swappable. I'm considering getting another one!
I think it will depend on what you mean by "good deal," though. My Urban was cheaper than my Studio and was an OK pen, just IMO nothing spectacular and not for me.
