I have learnt some hitTest methods and I dont know what is best for games as in performance wise. There are so many collision tests and I am not sure what is quickest or slowest.

I have a player image which takes on many images like walking that I move with keyboard.  
I use bitmaps and test bitmapData using Bitmapdata.hitTest.  
I want to test against an enemy image where it again is an animated image.

My idea is to test the player image and enemy image with a simple rectangle test to see if they overlap and if they do then do a points array test on the image to see if any point hits on a pixel test.

I have read hitTest ,HittestPoint and Hittest with bitmapdata,spriteMovieClip, and testing bitmapData with rectangles, points or another bitmapdata.

For a game is/is not acceptable?
