You have to find the one that works best for you. In my opinion, the best way is research combined with trial and error. No doctor will know 100% what is right for each person- and in many cases they push a particular type or brand that they like, or that they get samples of, rather than what may be right for you. Many doctors do not listen to their patients well enough, so it's up to you to be vigilant in learning what is right for your body.
So. You have your high/low estrogens and your high/low progesterins. Those are two different hormones and if one pill that uses one dose doesn't work well for you, you need to play around to figure out what works for you. Some also mix the types together, and later one of my links will help you figure out if that's right for you.

Will it affect your fertility?
No. Whether you take inactive pills for four or seven days out of 28 days, four or seven days out of 84 days, or continuously with no inactive pills, birth control pills simply put your fertility on hold. They do not reduce your ability to have a baby.
The important issue is to take your pills correctly to avoid pregnancy.
Birth control pills do not protect you from STDs. Unless you're in a stable, long-term relationship with someone you trust absolutely, you still need to use condoms. Before having sex with a new partner, you should both get tested to make sure you're free of STDs. http://www.mayoclinic.com/health/no-period/MY00974

(at the end it says that no long-term testing has been done on anya/lybrel yet, so unless it's chemical makeup is remarkably similar to the other types, I'd hold off on this one personally- however it seems to just be taken 365 days a year, which any pill can take away your period by doing. dose is probably adjusted for this.)

I do not personally recommend the patch. While it did take away my periods, it was unsightly, can cause a skin intolerance to medicinal adhesives (it's like a band-aid) which gives you a rash, and often doesn't stay for the whole week (especially if you shower a lot/bathe/swim) without being taped down. It has also raised concerns about doubling certain risks over the pill or other methods which you can read more about here (item 10 and 11).
