I went from the HTC EVO LTE to the S3 to the Note II to the HTC One. I've noticed the HTC One has stronger radios as opposed to the S3 and the Note II. The HTC One can pick up the wifi signal from my home wifi several homes down, whereas I did not get any signal on the S3 and Note II from that same distance. At work we have the top 3 floors of a 12 story building, whether I'm inside or outside the HTC One immediately picks up our company wifi, not the case for the S3 and Note II. I rarely got a 4G signal on the S3 and Note, the HTC One picks up the signal right away. In my personal experience I can say the HTC One does have stronger radios.
