It's not just a matter of AT&T/TMo vs. Verizon/Sprint. It's not just GSM service vs. CDMA.
Your problem doesn't sound like a coverage problem, rather it sounds more lik a building penetration problem (based on the examples/questions you raise).
Typically, CDMA will have better building penetration than GSM. More importantly, though is the frequency. The higher frequencies (like AT&Ts older 1900MHz range) don't penetrate buildings well, whereas the lower frequencies, like their 850MHz frequency, tend to do better. That's part of why the 700MHz auctions erlier this year were so important to the winner.
What you should do is find out what frequency tower signal you are picking up. I'm betting you're in a 1900MHz zone. I only wish somebody would product maps that showed the coverage as a function of frequency rather than just "carrier" coverage.
Where I am, Verizon/Sprint cover well - but only if you are near the freeway. AT&T / TMo cover more area, but coverage strength is often mediocre. Not a great choice to have to make! The 3G expansion plans of the big boys are starting to change that landscape, however - stay tuned!
