It's a tough call for me.
I loved Kathreya's eviction, my evil side was really glad she was booted out in such a mean fashion (and she cried/sobbed/broke down so much).
Stuart from BB5 was also amazing, first suprise eviction in BB but the reception from the crowd was immense and so nice to see a housemate being cheered so much and he deserved it, he was a top guy.
Stuart (BB9) crowd diving but actually face planting the floor was hilarious as was Marco's running slip which took him and his mum down.
But just edging it is Vanessa (BB6). HA! Lies, deceit, confusion, the housemates having to pick who went, tears, weeping, an orange pummeled into Vanessa's face. What was there not to love about that eviction?
