If you want the best chance for an airline, go to ctc and do their integrated course, they have the sim's and the contracts etc.
Stapleford are very good if on budget, modular and want to get through quickly as they are very organised. Some of their IR instructors, also fly commercially on their AOC and head of training very experienced airline pilot. Stapleford maybe cheaper than training at shoreham. When considering Southend is local for ILS training, where you can do vfr general handling on the way back. Stapleford does not charge for landing / circuits like shoreham, which is now very expensive. Do your own research and make a informed decision that works for your situation.
