Search on JD Power and Wireless to see what the real ratings are - by region (a couple of examples here and here). AT&T competes with Sprint for last place across the board. T-Mobile and Verizon are at the top. Maybe you just don't understand good quality when you see it. Maybe you buy in to AT&T's hype (long ago debunked)Another thing about AT&T is their prices. They're a bit pricey but it's worth because they have the best service and your calls don't drop. Just check the service map on the AT&T site and see if you have enough coverage in your area and if the service is right for you.
Someone correct me if I am wrong but CDMA (Verizon and Sprint) is able to penetrate buildings better than GSM (ATT and TMobile).
I was told this a few times. Maybe someone can shed some light on this?

You might be thinking of cell radio frequency (band). Verizon's network has a large proportion of 850 MHz towers and some 1900 MHz towers (the two frequencies used by CDMA in the US). Sprint's tower's (the CDMA ones, not the iDEN ones) are exclusively 1900 MHz. Watt-for-watt, lower frequencies have better structure penetration which gives Verizon an advantage over Sprint. Additionally, the 1900 MHz towers are limited by the FCC in output power. So, in general, Verizon has better building penetration than Sprint, but because Sprint roams on Verizon's network, the difference is diminished somewhat.Someone correct me if I am wrong but CDMA (Verizon and Sprint) is able to penetrate buildings better than GSM (ATT and TMobile).

In the GSM world, AT&T is also heavily into the 850 MHz band while T-Mobile is in the 1900 MHz band.
So, the answer to your original question is: It's impossible to say. Verizon and AT&T will have similar building penetration while Sprint and T-Mobile will be similar to each other. However, other issues come into play like proximity of a tower, phone sensitivity, addition of repeaters (common in big buildings like airport terminals and skyscrapers) and overall tower availability (maxxed out by subscribers/shortage of bandwidth). Your individual situation will drive the answer to you question.
