  Neither is faster in general. Move to PostgreSQL to drop per-core licences, run on any host and gain its types and extensions. Move to SQL Server for the Microsoft data stack, columnstore analytics, or a vendor that certifies only it. Migrate only when that gain beats the cost, which is in the code (procedures, dialect, collation, locking), not the data.
