1600 List Problems

So I've made another few army lists for the tournament and not sure which I prefer. In list 1 I like the targets, and the Gutter Runners. List 2 could do alot of damage in combat and list 3 is a normal Skaven tournament army. List 4 has the Clanrats changed for the better looking Stormvermin. Again it's 1600 points, no Lords, no duplicate war machines, max 40 in a unit, no Doomrocket.
