Suno and Udio are the two most-compared AI music tools, and both are good at English-language songs. The differences are mostly about control and community.
Suno's strengths
Suno tends to produce consistent, well-structured full songs and has the larger community, so there are more tutorials and shared prompts to learn from.
Udio's strengths
Udio has a reputation for clean English-language audio and finer editing control, which appeals if you iterate carefully on a single track.
The third option for Indian creators
Both are built around English. If your songs are in Hindi, Punjabi or another Indian language, Autunes (powered by the Zori models) is competitive on quality and clearly better at authentic Indian-language vocals, with bundled tools and a generous free tier.
