Really recommend you not to make decision based on money as first criteria.
Think long term and imagine what you want to be in 3-4 years. Then assess which one will provide better platform ADL or Deloitte.
Worklife balance would be something elusive in consulting firms so I would not put too much emphasis on that.
Another suggestion is to talk with ex-employee of ADL in LinkedIn. Send as much as cold inmail as possible and connect with the ones that reply. They will be the best source of input
