Anyone saying Pete used to beat Kingpin more often than not is wearing goggles from the 2000's. Not only did Fisk usually win, his only losses to Spidey until about 2008 came through plot devices.
The reason I made the KP respect thread was because when I was putting together the Spidey respect thread (the original one, not the current one), I couldn't believe how great Fisk did against him. It wasn't once, twice, plot devices, etc. It was ALWAYS. And then he'd perform an independent feat to confirm his level, like making a fool of Cap or Batman (both of which he did, albeit in a non-canon crossover for Bats) or easily crushing steel in his bare hands.
Also, for those trying to claim otherwise, his victories and stalemates against SM continued to come well after SM had been established as Class 10.
In other words, this fight isn't even close. Bruce would survive for a bit, get in some good strikes, and lose. Classic Kingpin 9/10
