Undoubtedly the seats will feel much more crammed than previously, because the magazine space takes up about 2" of space right in front of your face. So, whilst your knee space will have increased, your face space will have reduced (I've flown these seats many times in Europe, so I do know them quite well) and you will feel closer to the seat back.

And forget about using any sort of normal-sized laptop, even in E+. The protrusion from the magazine space is too great.
