Tawny Eagle v Black-chested Buzzard-eagle
#1
Black-chested Buzzard-eagle - Geranoaetus melanoleucus
The black-chested buzzard-eagle (Geranoaetus melanoleucus) is a bird of prey of the hawk and eagle family (Accipitridae). It lives in open regions of South America. This species is also known as the black buzzard-eagle, grey buzzard-eagle or analogously with "eagle" or "eagle-buzzard" replacing "buzzard-eagle", or as the Chilean blue eagle. It is sometimes placed in the genus Buteo. This is a huge eagle-like "buzzard" ("hawk" in American terminology). It has a total length of 62 to 76 cm (24 to 30 in) and a wingspan of 149 to 200 cm (4 ft 11 in to 6 ft 7 in). In the nominate race, males averaged 2.13 kg (4.7 lb) and females averaged 2.75 kg (6.1 lb), with a range between both of 1.67 to 3.17 kg (3.7 to 7.0 lb). In the linearly slightly smaller G. m. australis subspecies, a male weighed 1.7 kg (3.7 lb) and a female weighed 3.2 kg (7.1 lb), indicating the bulk of the two races is roughly the same. The food of this carnivore consists mainly of mid-sized mammals; the introduced European rabbit (Oryctolagus cuniculus) seems to have become a key prey item. The black-chested buzzard-eagle is helpful to farmers by keeping down the numbers of the rabbits, which can be serious agricultural pests. Among the native fauna degus (Octodon) and hog-nosed skunks(Conepatus) are important prey, but mammals as formidable as a gray fox (Urocyon cinereoargenteus) – two to over three times as heavy as the birds and certainly not defenceless – are occasionally hunted and killed by this hawk.

Tawny Eagle - Aquila rapax
The Tawny Eagle (Aquila rapax) is a large bird of prey. Like all eagles, it belongs to the family Accipitridae. It was once considered to be closely related to the migratory Steppe Eagle, Aquila nipalensis, and the two forms have previously been treated as conspecific. They were split based on pronounced differences in morphology and anatomy; two molecular studies, each based on a very small number of genes, indicate that the species are distinct but disagree over how closely related they are. It breeds in most of Africa both north and south of the Sahara Desert and across tropical southwestern Asia to India. It is a resident breeder which lays 1–3 eggs in a stick nest in a tree, crag or on the ground. Throughout its range it favours open dry habitats, such as desert, semi-desert, steppes, or savannah, plains. This is a large eagle although it is one of the smaller species in the Aquila genus. It is 60–75 cm (24–30 in) in length and has a wingspan of 159–190 cm (63–75 in). Weight can range from 1.6 to 3 kg (3.5 to 6.6 lb). It has tawny upperparts and blackish flight feathers and tail. The lower back is very pale. This species is smaller and paler than the Steppe Eagle, although it does not share that species' pale throat. Immature birds are less contrasted than adults, but both show a range of variation in plumage colour. The Tawny Eagle's diet is largely fresh carrion of all kinds, but it will kill small mammals up to the size of a rabbit, reptiles and birds up to the size of guineafowl. It will also steal food from other raptors.

As formidable as the buzzard eagle is, the tawny eagle would be the one that robs it as it has attempted to rob even the powerful martial eagle.

for me the Geranoaetus melanoleucus is much more aggressive and it fights body to body with the Andean condors (they weigh up to 12 kg and triple the size of the Geranoaetus melanoleucus).

That is impressive considering andean condors have even fought off golden eagles.

Since, condors have tough off golden eagles, I doubt the buzzard eagle can kill a condor. Tawny eagles have faced off Marabao storks and even mobbed lappet faced vuturea (which are way more powerful than condors).

The Geranoaetus melanoleucus is a very aggressive raptor at the time of fight, has been observed to kill scavengers (caranchos and chimangos) and has also been seen attacking in the air crowned eagles and condors; in Cordoba it was observed as a geranoaetus melanoleucus stole the comfort of a large crowned eagle. 
they are very territorial birds and get angry easily when other raptors enter their territory.

is a territorial and aggressive raptor that lives in combat with other raptors, are very prepared and accustomed to the fight

The chillean blue eagle being able to take on a grey fox is impressive considering the grey fox is more aggressive than the red fox.
