BIAB is still best in class (even if the UI is practically Soviet era) simply because of the sheer number of RealTracks, which are actual performances by musicians that dynamically adapt to your chord progression.

I’ve actually taken some of my own compositions and run them through Suno using the “Cover” option, and it’s pretty nuts what it can do.

What would be really cool is the concept of combining a physical arranger keyboard (like a Yamaha PSR-SX) with real-time orchestration produced by a backing generative model.
