Waved blades debate - combat value

[Radu Transylvanicus]

Many blades from many parts of the world are forged waved, from the kris and keris of the Malay world to European daggers to Hindu blades. I came to the conclusion of the waved blade being pure fashion statement but I want to challenge other opinions of any opinions, pros and cons of a waved blade. In European culture wavy blades seem to retain the names like “flamberge”, "flambards" or "flammards", basically meaning flamming.
The only difference is perhaps that a same sword with a waved blade would rather give a more of a chopping cut versus a traditional slashing cut of a standard blade.
Few examples:
