In RES, it’s one command to see them all at once, and just the SB’s, not everybody. You also don’t have to do it for each equipment type, and each seat. Although, these days it would indeed only be two N3D’s with only EMB in the Base. The RES one also shows which SB they’re doing.

The biggest advantage to RES is quick listing for flights on the fly rather than resorting to the NRTP.
