The difference between the two is that useless midd is a fraud and WB is a legend
A legend who was too much of a coward to go and save Oden and also go after Blackbeard for killing Thatch. Also acted like such a baby when Roger wanted to go with Oden too and threw the biggest, most destructive tantrum too.
He also ignored Shanks' warning about Blackbeard, despite knowing full well how much of a threat and POS Blackbeard is from decades of first hand experience of having him in his crew, then died without ever accomplishing anything of value and his washed up crew are a complete joke and irrelevant now. Some rival to the "great pirate king".
Meanwhile you guys still can't come up with anything more original than "hurr durr, Useless Midd", repeating the same insults like broken records or NPCs.
But I'll give you credit, if Whitebeard was real, maybe he'll let you ride his "Moby Dick" though and let you call him "daddy".
