Larry Holmes was unquestionably the best of his era, so he gets a high score in my book. But not quite as high as some have him. His reign was long in both years and defenses, but in my opinion weak. Not including the shadow of Ali, he never beat a true ATG, except possibly for a likely declining Norton, who he got a fairly controversial win over. On that note, three of his championship wins were controversial, if he had been given losses to Norton, Witherspoon, and Williams, and all else was as much the same as possible, his reign would have been cut up into ribbons. Also, while imo he never really avoided anyone, he also never tried to unify any of the belts, and that cuts against him. All that said, he was top 5 in most types of longevity records for HW championships, and above all other reasons that puts him in good stead. I have him at 11, but top 10 would be very fair.
