What are the advantages and disadvantages of normal, swept-forward, delta, and swept-back wings in airplane wing design?

Normal swept back wing technology is the most mature, good low and medium speed performance, high speed performance can also be, belongs to a more eclectic design;

Forward swept wing has more excellent low and medium speed performance and hovering ability, but the wing is heavy, the design is very complex, immature technology, high speed performance is very bad;

Delta wing design high speed performance is very excellent, but the low and medium speed performance and the ability to hover is very poor, so these aircraft are very clumsy;

Variable swept back wing design is very good, but it is very bad, so it is very bad.

Variable swept-wing combines the advantages of normal swept wing and delta wing, and at the same time can overcome its deficiencies, the pilot can manually or automatically adjust the wing state according to the aircraft's flight status, with the full altitude and full speed of the exceptionally excellent flight performance, typical of the F14, but its variable wing system is mechanically complex, high failure rate, heavy weight, complex design, high cost of the aircraft. Complexity, high cost of the aircraft, so now the aircraft has basically no longer use this design.
