Finally a good battle. I imagine most of you are tired of spite/troll threads so here's some real food for thought.
Simplified OP: There's 2 identical Cells and 2 identical Buus. Cell absorbs a Buu using the same type of absorption he used on androids, and the surviving Buu absorbs the other Cell. For both Cell and Buu, the absorption technique was 100% successful.
Edit reason: people didn't seem to be reading the original OP or are too dumb to understand it.
Second edit reason: Cell has 2 types of absorption. Edited to clarify which one.
