I'm considering taking birth contol pills which pills would be more effective if im still a teen?

All are good. I tell young patients the best birth control is the one you will actually use. Choose a brand of pills that is inexpensive or that your insurance covers. Also consider birth control methods that where you dont have to do something every day. Read about mirena, (levonorgestrel) implanon, paragard, NuvaRing and orthoevra patch. You have lots of options and avoiding an unplanned pregnnacy is important.
All are fine. There are advantages and disadvantages to all the types of pills but any combined estrogen/progesterone pill should be effective for teens.
