For Eberron lovers, do you view Ravnica as competition? Both are mainly urban and ubiquitous magic.
Not really. They play to different campaign hooks, themes, and even aesthetics.
A neat feature of Eberron is the absence of nature. Or rather, nature is pushed into the background while psionics and elementalism are pulled into the foreground. Thus background and foreground contrast each other and heighten each other.
Of course, focusing on a nonurban region in Eberron reverses this, where nature becomes the center, and psionics and elementalism are distant contrasts.
Most of Khorvaire is actually rural. Many of the nations that broke away from the Five Nations of Galifar are also fairly non-urban too. And the nation of Cyre, which used to contain many major cities, also is now a smoldering wild magic wasteland. Across the ocean, both Aerenal and Xen'drik are mostly jungles. While the urban fantasy and cityscapes are commonly marketed for Eberron, it has a LOT of wilderness, nature, and rural areas.
Does it have Dragonborn in it? If so, don't care. 3e Eberron, the way it was intended or nothing.
The way it was intended? If you knew anything about Eberron, then you would know that is ignorance talking. Let's look at #1 on the list of 10 Things You Need to Know About Eberron (ECS p.8): "If it exists in D&D, then it has a place in Eberron."
Eberron was intentionally written to be inclusive of all D&D content at the time of 3E. In fact, 3E arguably does not even represent Eberron "the way it was intended" once you realize how much was changed, inserted, and rewritten from Baker's initial draft and sales pitch to the final product. WotC basically reworked Baker's Eberron for 3E fairly extensively. Fairly certain, for example, that shifters, warforged, and kalashtar were actually "forced" into Eberron by WotC because Wizards wanted Eberron to feature new character options. Halflings riding dinosaurs also came into the picture at the point when WotC was editing the project. This is not to discredit the creative genius or input of Keith Baker, but Eberron was a a team effort and "the way it was intended" emphasizes point #1 above: Eberron is inclusive of whatever D&D content you want to use.
