T-Mobile has successfully managed a CDMA merger (MetroPCS) and subsequent re-farming of spectrum to their GSM-based LTE stack with minimal disruption. (they basically put the CDMA 1X bands into the HSPA guard bands, announced a sunset date, and closed it)
Where Sprint's merger would suck (amongst other things) is that they were wholly too incompetent to launch a modern IMS (voice-over-LTE) network where MetroPCS was able to do so.
