SAP BW has been in the market for the past eight years and CRM is relatively new. You will see more job requirements in SAP BW and for the same reason you will face more competition. Just a training won't be good enough to have a good career in any area. It is the effort you put in that counts. My suggestion is whichever area you choose, gain very good knowledge and experience in that area by giving your best effort.
