PVA is printed in BB cores only on an Ultimaker 3. However, you can print everything with a BB core, Cura and the printer give you warnings bet let you override them. You will get significant oozing for PLA in a BB core. For two-color prints you use two AA cores; that's why every Ultimaker 3 comes with two AA 0.4mm and one BB 0.4mm core.
The mechanical difference between AA and BB cores is the internal geometry of the nozzle.
