Aztec Hawk 7 vs Coleman Darwin 5

[scarymamma]

Aaaahhhh, about to go absoltely bonkers!!!
Can't decide between the Aztec Hawk 7 (2 bedroom, 7 berth + SIG) or the Coleman Darwin 5 (2 bedroom, 5 berth + ZIG) We are a family of 4 so the extra space in the Aztec would be great, but the Coleman seems to have natty little design extra's (like a storage space behind the bedrooms), it also looks like it might be easier to erect (but I could be wrong!). Has anyone already got one of these tents and what do they think?!? Trying to make a decision is making me go grey!
