Only in the same narrow way that a camera makes better art than a painter. Or the idea that a generic landscape print is better than a Rothko, because it looks more like other paintings that you like to look at.
In the same way, Suno can produce music-like audio very well. It doesn't produce music. It may be possible for somebody wielding Suno to produce music, but the average use of it certainly isn't it. It's certainly worse at producing music than almost any musician.
It can churn out muzak like no tomorrow, though, same as ChatGPT can render you barely-tolerable images of any art style you ask for.
Technical ability does not define if music is 'better' or not. Art is a conversation between the artist and the audience. If there's no artist there, there's no conversation, and there's no art.
