Basically they're 2 different radio technologies for cellular phones. As for coverage, it's less about GSM vs. CDMA than it is the deployed network the cell provider has. I carried a Cingular GSM and Verizon CDMA phone for the last 10 months and around the valley I found pretty much equal coverage/strength. But when I traveled it was a mixed bag. For example, I had better luck with my Verizon phone at CCR, but the Cingular was better in Eastern Arkansas. I think it really depends on where the provider has the most market penetration that determines how much they invest in the network deployment. On a nationide scale, Verizon probably has the biggest/most dense compared to the rest, regardless of phone radio technology.
The downside of CDMA phones is that there is no way to adapt them to other networks without paying fees (like with Verizon). GSM phones allow you to change out the SIM card to match the network you are on. Of course, many GSM providers lock their phones so they can't be easily used on other providers' networks.
