I don't have a favourite HM this year but I would have no problem with either Keith or Katie P winning.
They seem like nice people who don't have a chip on their shoulder.
Kav & Calum have shown they have a nasty streak & Michelle has been quite two-faced.
Katie H......well the less said about her the better.
As far as Perez winning, I would not mind. Purely to see Katie H screwed up face of shock when it happens
