Alicia,
Just a quick reply to your query,
1) Ctc is a structured modular course, not integrated, though most employers don't seem to mind one bit.
2)It isn't sponsored, but you are " insured " against failure by having 30 grand of the training paid for you if u don't meet the standard. Not bad really. Yes Ctc provide a type rating after the MCC/JOC, specific to the airline you are going to work for.
3) Yes. How many other schemes almost guarantee a job at the end as long as the airline doesn't go bust...er...very few, and certainly no schools that i know of. None of those three that u mention even come close in that respect.
4) The people, on the whole they are pretty damn good, dedicated and wanting to make you a success in your career.
hard decision i know, but shoot for it, you never know it might just work out
