PCB land pattern soldered BGA? I have seen a describtion in IPC-7093 6.1.3.6 solder mask design. NSMD is better than SMD on QFN solder joint strenth

? I have seen a describtion in IPC-7093 6.1.3.6 solder mask design. NSMD is better than SMD on QFN solder joint strenth. Should I assume that NSMD is first option for other chip, sop and connectors
