The original cover of Juujou Yuujou is an excellent example of how Okayu has improved significantly as a singer since then and Korone has not. That's not a slight against Korone, it's simply the truth owing to the fact she doesn't really seem interested in becoming an amazing singer, which is fine. Their most recent performance of it at the live perfectly displays this as their harmony was almost non-existent and Okayu had to sing more flatly to be in line with what Korone was putting out. The DaPump "cover" is really just them goofing around and I wouldn't use it as an example of their singing ability or harmony.
