What is the best pixel perfect method?

Hi, I’m trying to choose which pixel perfect method should I use.

I’ve seen at least 3 that seems to work pretty well but I don’t know which one is the best in terms of performance and final effect.

I don’t know if you use any other method but any suggestion is helpfull, so share it with everybody ^^

Thanks for you help!
