N8ter I agree that the attraction of cdma is network reliability and building penetration. I live around Lake Charles, LA and I have few issues with dropped calls compared to friends on AT&T. I've never compared data speeds, but I have no trouble streaming YouTube and music here and Lafayette. I am looking forward to 4G though. The Verizon store here has told me sometime this summer it will be here. In the meantime they are selling 4G androids like hotcakes.

I lived near Lafayette, went out sometimes in Lake Charles and Baton Rouge.
A GSM device (T-Mobile or AT&T) will steamroll the 3G speeds of a CDMA device in Lafayette. Lafayette is an HSPA+ market for both T-Mobile and AT&T, and 3G HSPA devices benefit from the enhanced backhaul. My AT&T and T-Mobile devices could easily get 3Mbps down. The max theoretical of a CDMA Rev. A device is 3.1 Mbps down and about 1Mbps up. My Vibrant was routinely 1Mbps above both of those in Lafayette and even in Scott, La outside of Lafayette.
There is no way for a CDMA phone to outperform that, because it's a theoretically impossibility given the cell radio in them. There are people who got over 5.5 Mbps down on a Vibrant on 3G. That's almost twice the theoretical maximum speed of a CDMA device.
The only time a CDMA phone will outperform a GSM phone for 3G speeds is if it's a slower 3.2 mbps 3G GSM device (likely in a decently conjested area - these are devices like a Samsung Jack or Blackberry Curve 3G), or the CDMA network is factorably underused compared to the GSM network in that area, allowing the CDMA phone to get higher speeds by virtue of that component.
HSPA/HSPA+ has always had higher speeds. That is why AT&T was consistently the fastest rated 3G network prior to the HSPA+ and LTE "4G" roll-outs, despite their issues (and they've put up tons of towers since then). Verizon and Sprint were almost always slower than both AT&T and T-Mobile.
It's not even really debatable, TBQH...
Like I said, there are areas where CDMA may sport higher speeds than GSM. That all depends on the area and network load. However, all things being equal, HSPA/HSPA+ will embarass CDMA's 3G speeds - easily. This is fact.
People picked Verizon because their network is rock solid for calls and things like that. 3G speeds only really became a huge focus for consumers in the past 2-2.5 years when people started streaming tons of media nad things to their phone.
You can stream YouTube HQ without any issues on a phone with a sub-1Mbps connection, and you can stream whole Netflix Movies on a 1Mbps internet connection through WiFi (been there, done that), so that doesn't really say anything for a network speed comparison. That can often be written off as "placebo."
