Yes it does seem brighter. I use to see my aux lights to either side of the low beam now they are covered by the light that is focused in a rectangular pattern that is higher towards the right side of the road. That might not work well in the UK. The high beam seems brighter.
I too had a 'fogged' lens. I was able to use some tools to clean the inside of the lens. It is much better but I too would like to replace the chrome plated plastic headlamp reflector with a glass unit. Is the Adjure unit a glass or plastic reflector?
I think the stock lens and housing is poorly designed. I could never get it aimed so both beams provided adequate lighting. With the above set up and 2"@25' aim its great.
