Samsung Focus S

Resting amongst four Android phones and the iPhone 4S you will find the Samsung Focus S listed as one of the five best AT&T Smartphones. CNET gave the Windows Phone a 4/5 star ratings while the average user rating is half a star higher.

According to CNET, the bottom line on the Samsung Focus S is:

Bolstered by a brilliant display and strong hardware specs, the Samsung Focus S is arguably the best Windows Phone ever released.

While CNET recognizes the large screen (described as gorgeous), a good 8mp camera and HSPA+ speeds they feel the thin form factor lacks durability (can't say that we necessarily agree).  Regardless, it's nice to see another Windows Phone catching the spotlight.
