Good list of stuff. The WBO has issues at 147 with that particular title being a Top Rank belt and it's no secret. It is blatantly held hostage at one promotional company and has never left since 2006.
Sad that the least corrupt, the IBF are the worst IMO. Their mandatory enforcement doesnt allow for rematches for long time Champs, doesn't always allow unifications, and forces many of their titlists into BS fights every 18 months, while a Champ is ironing out a big fight, often being so strict that they force Brook to fight Dan and Bizier while he was working on a fight with Khan, Thurman, Pac, or Bradley. WTF......Dan and Bizier over the above mentioned.
WBA should naturally be the most respected since they are the oldest and have the longest tradition. Unfortunately they still have all those "regular/super/interim" champions and it should be their priority #1 to establish a single champ by division as soon as possible. I'd say the WBA has much more self respect than WBC (for example refusing to sanction GGG/Brook, potential Floyd/McGregor fight etc, while WBC usually sells their own dignity and even creates a "special" belt whenever a good money fight is there). WBA still have their fair share of corruption though. WBC has always been trying to "market" itself and create a perception of a leading organization with their "green" belt (at least among Mexicans). However, they are so inconsistent and selective in applying their own rules that they have almost become a laughing stock. Some boxers they dearly protect either by allowing them to avoid mandatories forever, or by installing joke #1 contenders. Notorious for corruption and pushing their agenda. Clown Sulaiman being the president doesn't help their credibility either. IBF is at least strict about mandatories (which is usually a good thing, but not always). However, their rankings have always been very bad and heavily influenced by certain promoters and managers. WBO may the worst. The youngest recognized organization and usually in a pocket of a couple promoters. Very selective application of rules, bad rankings and they don't even seem to pay attention to the mandtories unless it's for a fighter promoted by a promoter which WBO closely cooperates with. In terms of historical prestige, I'd say 1-WBA, 2-WBC, 3-IBF, 4-WBO (from best to worst). In terms of current reputation and respect, it's really hard to say.
I think the WBC is the worst at the moment, Wilder had had five voluntary title defenses against winos from the alley.............next up...........Stiverne.........did not earn being ranked at all..................WBC also kisses Adonis Stevenson's arse...............they new P-U-K-E org. appears the best now......................let's face it, they are all crooks................although one has suspended some criminal judges for a change, but will that last?
the WBO until recently was not considered a major boxing org, so I have to say that one. In 10 years they'll make lists like this one with the IBO added into the mix.
Really though....................How can you pick the worst of the worst? (Note: The judge suspension really is a start or something, but that's only one org..............)
All four are equally bad, they are parasites on the sport of boxing. Boxing should be regulated by some international non-profit body that is sponsored by the U.N., or a consortium of nations that hold a lot of fights (UK, US, Japan, etc.), and this body should hand out the ONE belt. All these profiteering parasites should be drummed out of the sport, made illegal.
WBA in my opinion is the most "controversial." IBF in my opinion holds the least amount of clout out of all 4 organizations. I'd say the WBC and WBO are somewhat close, but clearly more reputable than the other 2 alphabet titles.
With their three WBA 'world' titles in each weight class, and judges who turn in some utterly baffling scorecards -- even by the standard of 2017 so far.
