Go for the most expensive one! Whoever they are. The industry needs the cash! And after you have spent the money, please don't ask when you are going to get a job!
The money that you are thinking of spending on a rating could keep you in beer and beans for two years or so. And think about this. Employers will still probably ask you to do it all over again, just so that you have been trained with the same SOP's as your colleagues. And bond you for it if you don't pay again! That's if they operate the same type as you have on your licence. And what are you going to do about line training - less than 500 hours on type and you are still very new!
Save the cash. Spend it on yourself. Let your employer pay.
