I now prefer the 1/4 mil chart especially when flying in Scotland. This preference came about because when I was struggling a little with my navigation my instructor decided it was because I was using a 1/2 mil chart. Once using the 1/4 mil chart my navigation rapidly improved. I will start using a 1/4 mil chart in the South East when the one I have on order arrives. On my QXC I took both the 1/4 mil and the half mil charts because of how one destination appeared on the 1/4 mil chart.
Charts are down to personal preference but you should make sure you keep at least 1 up to date and carry the up to date chart with you even if you are mainly using the other chart since there will be times when you will want to make sure you are using current information
