Having started my career with self-flown approaches, then transitioned to monitored ones, I’ve got used to the whole idea. Doesn’t mean it’s the absolute best for everything but I like the concept of at least one pilot thinking mostly about the G/A approaching DA/MDH. It also shares the workload, and involves the non-landing pilot in the operation to a greater degree than spending the whole flight watching someone else.
It also helps with stability. At 1,000R or whatever on a monitored approach, you have to assess how it’s going: if you don’t like it, you tell the other guy to G/A or simply do not take control, which effectively forces a G/A, which is easier to do than when you’re flying the whole thing and have fixated on the landing, with the PM on the edge of their seat.
On the whole, it’s a bit more CRM-y and inclusive, which is the way modern flying is.
