I think we take away very different things from Eberron. I don't see it as a particularly urban setting. Yes, Sharn gets quite a bit of attention (particularly in the Wayfarer's Guide), but so does Waterdeep in the Forgotten Realms. But other than that, there's lots of wilderness to explore and adventure in - the Shadow Marches, the Eldeen Reaches, and Q'Barra are all largely untamed wildernesses, and Valenar and the Talenta Plains are both dominated by nomads. Even the settled nations have large portions of wilderness and rural areas in them. And beyond Khorvaire, the entire continent of Xen'drik is there for wilderness exploration.
Neither would I call Eberron a setting where psionics and elementalism are in the foreground. Eberron has some spectacular features based on bound elementals, with the Lightning Rail being the foremost one. But other than that, it's mostly a curiosity. And regarding psionics, I would call it a setting that has a place for psionics if you want it, but it's not a front-and-center kind of thing. You could run a dozen Eberron campaigns without ever mentioning Riedra.
