You said the Giant costs about £40 (about $60 U.S., I think) more. The value you're getting for the money for each of them seems pretty close to me. The Giant seems to me to be the better bike--somewhat better parts overall, so if you don't mind spending the extra £40, that would be the one to get, IMHO. You do need to test ride them both though because one or the other may just strike you as right.
