The most recent release of SQL Server is SQL Server 2025, there is no SQL Server 2026.
As for which version to migrate to, I would say SQL 2025 if it is only a matter of the Database Engine. There may be some initial bugs, but SQL Server is a mature product, so existing features tend to be stable. If there are more glaring bugs, they are more likely to be with new features. But be sure to apply Cumulative Updates when they come out!
One reason I suggest SQL 2025 is that SQL 2025 will be in mainstream support for five years, while SQL 2022 only have two years left. Which means that you will soon be in for an upgrade again. Whichever version you move to, you will need perform testing, so that you don't run into issues.
When it comes to SSIS and Visual Studio, I can't speak to these, since I don't use them myself. My understanding is that it can take some time before full support for the new version appears on the tooling side. Also, while Visual Studio has the 2026 moniker, I would not expect it as such to understand SQL 2025, which was released later.
