Brygmophyseter shigensis v Cretoxyrhina mantelli
#1
Brygmophyseter shigensis
Brygmophyseter, known as the biting sperm whale, is an extinct genus of toothed whale in the sperm whale family with one species, B. shigensis. When it was first described in 1994, the species was placed in the genus Scaldicetus based on tooth morphology, but this was later revised in 1995. In 2006, it was classified into the genus Naganocetus, which is considered to be a junior synonym. The only known specimen, a nearly complete skeleton, was dated to be around 14–15 million years old. Brygmophyseter is thought to have been 7 meters (23 ft) long, and it probably had 11 or 12 teeth in the upper and lower jaws. Brygmophyseter is part of a group of macroraptorial sperm whales (often shortened to "raptorial") which tended to be apex predators using their large teeth to catch struggling prey such as whales. It had a spermaceti organ which was probably used for biosonar like in the modern sperm whale. The whale has made an appearance on The History Channel's TV series Jurassic Fight Club.

Cretoxyrhina mantelli
Cretoxyrhina is an extinct genus of large mackerel shark that lived about 107 to 73 million years ago during the late Albian to early Maastrichtian of the Late Cretaceous period. The type species, C. mantelli, is more commonly referred to as the Ginsu shark, first popularized in reference to the Ginsu knife, as its theoretical feeding mechanisms is often compared with the "slicing and dicing" when one uses the knife. Cretoxyrhina is traditionally classified as the likely sole member of the family Cretoxyrhinidae but other taxonomic placements have been proposed, such as within the Alopiidae and Lamnidae. Measuring up to 8 meters (26 ft) in length and weighting up to 3,400 kilograms (3.3 long tons; 3.7 short tons), Cretoxyrhina was one of the largest sharks of its time. Thanks to the discoveries of many exceptionally well-preserved skeletons of Cretoxyrhina, it is the anatomically best understood extinct shark to date. These fossils suggest that it may have had a similar appearance and build to the modern great white shark. The possession of extreme hydrodynamic features suggests that Cretoxyrhina may have been capable of burst speeds up to 70 kilometers per hour (43 mph), making it one the fastest swimming sharks. Its teeth were razor-like and had thick enamel, built for stabbing and slicing prey. Cretoxyrhina had large eyes that took up as much as one-third of the skull, and thus acute vision, suggesting that it used mainly eyesight to hunt prey. In a 2008 study, the lifespan of Cretoxyrhina was estimated to be 38 years, though a 2013 analysis reduced that to 21 years. Both studies found that Cretoxyrhina grew rapidly during the first few years of its life, doubling in size by three years of age and reaching sexual maturity at around four–five years of age.

Would you guys care to provide some reasons for your views?

Of course, the cetacean could head ram the shark or attack its unprotected gills. The shark's powerful slicing bite gives it a good chance to win if it disables a flipper.

The cretoxyrhina. It's larger, likely has the deadlier bite and its placoid scales would be more durable than whale blubber.

Brygmophyseter is apex predators using their large teeth to catch struggling prey, bigger head strikes the shark more power fully like orcs and liyvi do.and intelligent enough to attack on the weak points of shark.

Wider jaw+more teeth+slicing teeth vs longer jaw.

Megalodon vs livyatan.

I know.

Best example is orca vs gws fights. Orca hits gws with it's head and game over. 

And that head type more effective than orca.
