One data point: FOMA [1] in Japan was the world's first commercial 3G service to launch. Was it the "winner" of that "war"? No, it was basically an incompatible fork of UMTS [2] that in the end was used by nobody except NTT Docomo, who had to retool a few years later at considerable expense to be compatible with the global standard.
