If it's mostly for riding through London I would probably not consider snow conditions in the equation given how uncommon they are and how specific the tyre choice would be. Although a file thread would probably be fine for powdery snow and roll nice year round.
I commute on conti 4 seasons and never had an issue. Looking at replacing them with Marathon Almotion Evo when they are done
What sort of riding is this for? You are comparing really different tyres.
