Microsoft has already confirmed that Windows 11 version 25H2 has no new features over version 24H2. Both share the same servicing and pipeline channels, and so features that are build for 25H2 will also end up on 24H2, and vice versa. That also means there should be no app or driver compatibility, device performance, or platform stability discrepancies between the two releases.
You should still upgrade to version 25H2 however, as it resets Microsoft's support lifecycle clock and will receive security updates and bug fixes for longer than version 24H2. Version 25H2 will have 24 months of support from its general availability date, whereas Windows 11 version 24H2 is already a year into its lifecycle.
