When you add sweep you require a higher aoa for the same turn (and decreases maxCl), causing more drag. Swept wings tend to have a lower AR because the sweep gives a lower span.

The only advantage to swept wings is that you do not have to use a heavily refexed plank foil. The washout used in the typical swept wing to then counter the downwards pitching moment reduces high-speed effeciency.

That's why planks are better. Swept wings are better for combat because they are often more durable and recover faster.
