Agreed mate.
I never use my 18v impact wrench to crack wheel nuts, always by hand first, it can do it but why make it work harder than it has to. The OP never specified what he actually wanted to do with it he could be a chippie like 89gqpatrol4x4 during the week so the 1/4 drive would get used a lot then what the use of a wrench on the weekends and while the bosch unit doesn't quite have the grunt he will still only require 1 tool without the risk of break adaptors as that's very possible when turning 1/2" sockets.
