Perm staff have aws, so 1mth aws + 1mth performance bonus = 2 mths which is same as contract.

Perm is actually better because worse come to worse you still have guarantee 1mth aws. Contract is really depend, if they want to give 0 you also LLST.

NCS without good bonus is actually very low in total pay. For e.g. a Project Director is only paid like 9k x 14.5 mth include bonus only 130k which is a joke as many mncs pay their non-managers higher than that.
