GSM has poorer penetration into buildings, and Cingular's GSM network is not comprehensive -- there are gaps.
In GSM's defense, what you're refering to is the 1900Mhz network compared to CDMA's 900Mhz. However, as you may be aware, Cingular is rolling out a network in the 850Mhz band, which has equal penetration into buildings as CDMA.
As for gaps, yes, they have more gaps. GSM is newer in North America, so they are still catching up. It would be like saying CDMA has gaps in Europe...
