Types of milk powder for supplementing baby chinnies

Dear all,
wat brands of milk powder have u tried to supplement the bb chins with? How do they differ in terms of which is better or easier for the kits to take in and what else do u add in (e.g gerbers?). When is the age to stop handfeeding the bb as i didn't really handfeed the kits during her first preg.
