Its gaining some recognition, no corruption, interim/ super champions. They allow unification bouts and have computerized ranking system. The others have ranking boards which have been paid off in the past.
Nope. None of the belts mean much but if they have to be ranked: Ring WBC IBF WBO WBA IBO is a joke belt compared to the joke belts.
Yes it's the IBO championship belt. It's not as importnt as the Ring, WBC, WBA and IBF championships, but you usually have to be pretty good to win it.
Like every other belt, it's as credible as the boxer whom holds it. When Pacquaio beat Hatton, Hatton had the IBO belt, none of the other belts, but it was the most important 'cause you had to beat the lineal champ to win it.
E.G if Wlad relinquished all his belts other than the IBO then the IBO would be the most prestigious as you'd have to beat Wlad, the best in the division, to win it
