Sprint's EV-DO network is quite a different beast -- by far faster from my experience (and I've used both very recently). Now, truth be told, I've only used Cingular's HSDPA network in one market, and it performed admirably when I used it. But, Cingular's HSDPA network is nowhere near being available nationwide. Sprint's EV-DO network, which not covering their entire native national network, is built out quite a bit more than Cingular's HSDPA network, however.
So, what's all the fuss about? See this recent full-page ad in the September 5, 2006 edition of The New York Times:

It's that first bullet comparison that kind of piqued my interested. What does "largest high-speed wireless data network" mean? EDGE certainly does not qualify for "high speed" from my experience -- it's barely better than a 56K dialup connection.
I then snooped around Sprint's website to find this rather detailed comparison. Sprint, it looks like, directly responded to Cingular with some pretty good facts about its network. What was the comparison made of? Well, Sprint was comparing apples-to-apples as best it could. It was looking at it's nationwide (to a point) EV-DO network to the best comparable nationwide network Cingular offers -- which is the older and slower EDGE network (as Cingular's HSDPA network is not national, at least at this time).
So, after I researched a little bit more and contacted Sprint to gauge its response on Cingular's advertising (like I said in the title, "Round 1"), this is the picture that started becoming clear:
Cingular's claim of the "Largest high-speed wireless data network in America"
- From my information, 80% of Cingular's "high-speed" network is powered by its 2.5G EDGE network.
- Sprint Mobile Broadband (400-700kbps) is 5 times faster than Cingular's EDGE (70-135kbps)
- In terms of wireless broadband coverage, Sprint covers three times more people (153 million vs. 47 million), four times more cities (5,138 vs. 1.092) and five times more airports (486 vs. 95) than Cingular's broadband network, BroadbandConnect.
Cingular's claim of the "Largest Push to Talk network area coverage in America"
- Sprint's Nextel walkie-talkie phones connect instantly coast to coast with over 17 million people on what appears to be the world's largest walkie-talkie network.
- Sprint Nextel's arsenal of ruggedized devices and phones kind of gives a hard edge to Sprint here, as it has the only camera phone that meets military specifications for rain, dust and shock.
I guess "truth in advertising" depends on the eye of the beholder (and lawyers and interpretive double-speak). What else is new?

1. Great assessment. Heck, from the sound of it, it appears even Sprint's 1RTT speed in areas not built out is faster than EDGE. Just came back from a cross country trip and let me tell you, Sprint ROCKS! And from personal experience, Sprint is expanding their EVDO coverage.
If you haven't taken a look at Sprint Nextel recently, may be a good time to do so.
