Anglo's offer is for 1 year only. First Active's & many others have no end period. So less than 2 months after the year is up I'd have made more interest in the FA account than yours did in 12!
I think you might want to check your facts there mate. Where does it say First Active's account has no end period? Last I checked it was a variable rate and can be changed as and when FA decide. Anglo's account on the other hand guarantees 3.25% over ECB until June 2009, no such guarantee with FA. Can you explain your calculation where you would make more interest? My understanding of what you said is that it would take you 14 months to make what the Anglo account makes in 12 months??
Anglo is also more flexible in that funds can be transferred manually at any date during the month and no SO or DD is required. Far better account IMHO.
