Like it's been said, becoming a Supernova/Worst Generation, it's a pretty big thing. I feel like as a whole, I wish that Oda would have made all of the Supernova/Worst Gen (Luffy and Teach aside) easily comparable to each other in terms of strength and simply have Luffy edge the rest of them out as he is the one taking out the main force/enemy with every place they decide to help.
All of the Worst Gen are strong, but it just feels like Luffy just has way more tricks up his sleeve that will give him a better advantage. Granted, there are individuals whom we havent even begun to see the entirety of what they are capable of which is basically the rest of them aside from Law and Zoro whom I think we could see a bit more as far as Zoro is concerned.
And obviously, I want to see everything Drake is capable of.
Anyway, I wouldn't say that Apoo and Hawkins are failures. Every chooses their path/makes their choices. It doesn't mean they have to stick it out if it's not going well.
