I used the Jeremy Pratt/AFE series, I thought they were/are very good indeed, along with a latest copy of the PPL confuser (didn't buy the latter as one was passed around the flight school I went too!), made the exams easy enough.
The Trevor Thom ones have their fans but some think they are a little 'Dry' - quite what that means I'm not sure, I've only used his No.5 book for IMC and found it fine.
Didn't use any CD-ROM's so can't comment but the OAT ones seem popular with others.
