Why don't you feel 'comfortable' with a recognised training outfit?
What 'part' of CTC or Oxford Aviation do you not feel comfortable with?
Having someone in the 'industry' is irrelevant when it comes to training.
If you want meaningful, targeted advice then you need to say what the issue with the training providers stated is otherwise it's all guesswork.
AFAIK ab-initio training is pretty generic across the board for ATPL students irrelevant of which continent you are on, it's only the cost that varies.
