Which of these 3 series had a bigger impact? Which had bigger potential to return?

Teen Big Brother (2003) - a pre-recorded series saw eight 18 year olds enter the house as a replacement for CBB. HMs voted the evictees and winner.
Lasting impression: Since this series HMs in the main series have generally been younger

Big Brother Panto (2004-5) - basically a BB Allstars show on E4 which saw 10 former HMs (Mel and Nick from BB1, Narinder from BB2, Jade, Spencer and Tim from BB3, Anouska from BB4 and Kitten, Marco and Victor from BB5) form a pantomime to eb shown the day before CBB3 launched
Lasting impression: Ex HMs have returned to the house with Jade (BB3/CBB5), Nikki (BB7/CBB6 task/BB10 task), Alex and Adele (BB3/BB8 task) etc.

Big Brother: Celebrity Hijack (2008) - an E4 show which saw 12 gifted 18-21 year olds being controlled by celebrities acting as BB. Like TeenBB, it was a replacement for CBB.
Lasting impression: More interaction with the outside world such as having outsiders join the house for tasks e.g. Mohammed's brother and Nicole in a BB9 task, the boot camp, Queen and London tasks of BB10
