In brief: Always will be PPD+
Apart from the effectiveness debate, those who receive BCG as TB vaccine will always be ppd+ (or be hypersensitive to ppd) which can require imaging such as chest xrays to prove that there is no active disease, when previously a negative PPD would suffice.

In brief: Not very good
The BCG vaccine reduces the risk of children developing some of the more severe forms of active tuberculosis.
It does not effectively reduce the chance of becoming infected in the first place (which is what most good vaccines do). It is also a live vaccine which means it can have more significant side effects than other vaccines and cannot be given to immune compromised individuals.
