First of all, the Catholic Church admits that both Rome and Antioch (Orthodox) have a line of succession starting with St. Peter.
Speaking of the apostolic succession of Antioch, the Catholic
Encyclopedia says :
"The first Bishop of Antioch after St. Peter..."
Second of all, the Orthodox Church, which is not in union with the Catholic Church, also admits that both Antioch and Rome have St. Peter as their first Bishop.
Speaking of the apostolic successions originating from St. Peter,
OrthdoxWiki says :
After the Ascension, the apostles dispersed to preach Christianity to the world. They each founded different patriarchates. Some of the
most prominent disciples of Jesus founded the patriarchates that made
up the Pentarchy.
Jerusalem - James
Antioch - Peter
Rome - Peter
Alexandria - Mark
Constantinople - Andrew
Third of all, the Orthodox Church has always recognized that technically speaking Rome is superior to all of their churches in view of the Pentarchy. The only reason they go off the rails so to say is that, in a spirit of contradiction, they excommunicated the primate when he disagreed with them.
The Orthodox attitude to the Papacy is admirably expressed by a twelfth-century writer, Nicetas, Archbishop of Nicomedia :
My dearest brother, we do not deny to the Roman Church the primacy
amongst the five sister Patriarchates; and we recognize her right to
the most honourable seat at an Ecumenical Council. But she has
separated herself from us by her own deeds, when through pride she
assumed a monarchy which does not belong to her office … How shall we
accept decrees from her that have been issued without consulting us
and even without our knowledge? If the Roman Pontiff, seated on the
lofty throne of his glory wishes to thunder at us and, so to speak,
hurl his mandates at us from on high, and if he wishes to judge us and
even to rule us and our Churches, not by taking counsel with us but at
his own arbitrary pleasure, what kind of brotherhood, or even what
kind of parenthood can this be? We should be the slaves, not the sons,
of such a Church, and the Roman See would not be the pious mother of
sons but a hard and imperious mistress of slaves.’
Wikipedia relates to us that : Pentarchy (from the Greek Πενταρχία, pentarchía, from πέντε pénte, "five", and ἄρχειν archein,
"to rule") is a model of Church organization historically championed
in the Eastern Orthodox Church. It found its fullest expression in the
laws of Emperor Justinian I of the Byzantine Empire. In the model, the
Christian church is governed by the heads (patriarchs) of the five
major episcopal sees of the Roman Empire: Rome, Constantinople,
Alexandria, Antioch, and Jerusalem.
The greater authority of these sees in relation to others was tied to
their political and ecclesiastical prominence; all were located in
important cities and regions of the Roman Empire and were important
centers of the Christian Church. Rome, Alexandria and Antioch were
prominent from the time of early Christianity, while Constantinople
came to the fore upon becoming the imperial residence in the 4th
century. Thereafter it was consistently ranked just after Rome.
In other words, both Catholics and Orthodox believe the Pope is the successor of St. Peter. The difference being that Rome makes the difference between mere succession and the dispensation of the keys which would be considered final and most important succession. Therefore you cannot assume there is a bias in the lines of succession. By the way, Orthodox believe that the Bishop of Rome is the original Primus Inter Pares, a title of primacy which has now been usurped by Constantinople, although if unity is regained Constantinople will lose the title :
The Eastern Orthodox Church also uses the term "first among equals" in
regard to the Bishop of Rome during the first thousand years of Christianity.
Whereas the Patriarch of Constantinople is now
considered first among the Orthodox patriarchs, the Orthodox Church
considers the Bishop of Rome (regarded as the "Patriarch of the West")
the "first among equals" in the Pentarchy of the Patriarchal Sees
according to the ancient, first millennial order (or "taxis" in Greek)
of Rome, Constantinople, Alexandria, Antioch, and Jerusalem,
established after Constantinople became the eastern capital of the
Roman/Byzantine Empire. The Bishop of Rome no longer holds this
distinction in the Orthodox Church because, following the East–West
Schism, he is no longer in communion with the Orthodox Church.
Primus inter pares (Wikipedia)
Lastly, the list of Roman Bishops can be found easily but if you want to verify the validity of every individual instance of succession you'll obviously need to consult more precise ressources, like the Catholic Encyclopedia for all the instances of succession.
