Just because Cell claims to be a Solar System-level, and Buu is stronger than him? Is that why Buu is Solar System+? The only thing backing that up is them both being stonger being stronger than Frieza (Freeza saga version. Freeza is now stronger than both), who was able to destroy planets....in his base form casually, and it took like an hour to blow up a much smaller planet with the same attack...in his final form using actual effort......yeah....you see why Cell's claims do not work, and put him and Buu on a lower level than some think? Usagi may have had troble following her Nemesis feat, but that is because she started facing Galaxy-levels shortly after, then she fought multi-galaxy in the 4th arc, and finally universal in the final arc, before even becoming Cosmos.

The reason Usagi's immortality is believable thing is because it is her own future self telling it to her own past self. Cell however is telling it to his opponent to strike fear into them. Usagi however, as Cosmos is capable of fighting 1,000 years without resting for even a second, while fighting someone who can 1-shot the universe casually, which is a pretty good support to her claim.
