The combined pill(oestrogen and progesterone) which is usually prescribed is generally more effective (99%ish) than the mini pill (just progesterone 95%ish), but as for brands i really have no idea/ i'd assume they were all pretty similar as i doubt doctors would prescribe something that wasnt particularly effective :-)
For example, oestrogen can cause some peoples bodies to retain water thus causing them to put on weight.
does the progesterone mini pill hav side effects as wel, like water retention or weight gain?just wonderin cos i wana go on the pill, but dont like the side effects hehe, too dificult to please i guess
