fast way to copy texture data from one to another?

In openGL ES, what is the quickest way to copy one texture data to another texture (which is similar format)
I also want to be able to apply it on the DEPTH format + PACKED_DEPTH_STENCIL format

here is a few way i have found,

1. for color format, using GLSL and draw fullscreen quad (fast, but not work on depth)
2. PBO - (supposed to be fast, haven't tried it myself but some people claim it's slow)

thanks for all suggestions :)
