I've had some fun with Suno 5, but the songs absolutely don't replace well-made human music. They're much more formulaic and over-produced. They're usually forgettable. People I play them for can always tell they're AI produced.
I was very impressed with v4.5+ that I could get quite good songs evocative of Devo, Yeah Yeah Yeah's, Metric, etc.
Version 5 is currently harder (or I haven't figured out a way) to generate this kind of chopped/produced sound. It doesn't follow complex style definitions and tends to generate songs that are too slow and "smoothed" over.
