Much prefer Jonny of the two.
If you look at the 'friends' they''ve made in the house then you'll see that while Alex's ( Sandy, Adele, Tim ) were all negative and more to do with bitching than anything else, Jonnys ( Alison, Kate, PJ ) were more positive and more about enjoying each others company. That speaks volumes to me.
Also the bit about the polarity between Alex and Jonny fans on here, you find that the Alex fans are alot more vociferous and have more 'forum' inches, while the poll has them neck and neck. The Jonny witch-hunt last week from them got rather hysterical , and mobilised alot of Jonny fans to come out in support over the weekend. I can't see this ending til the last night to be honest.
