If you feel the need for change and some more competitive teams to play against definitely take the Benfica job. On an important note if you want to be accepted at clubs when applying you have to fulfil the boards expectations to get noticed. Otherwise you will be mostly rejected
Going to Benfica might open up new opportunities for you and a bigger budget to work with
Personally I would take it but if you feel at home with your team then it's up to you
