Is it only with OpenGL ES where PBuffers are faster at updating a texture than without one?(From what iv read in OpenGL ES you can "upload" faster with PBuffers than just using glTexSubImage2D alone. At least thats the method people are recommending.)
I have never heard of that, but I'm not using OpenGL ES much. This might be something hardware/driver specific. I don't think that you can say something like that in general for OpenGL ES. If PBuffers are faster, than a good driver implementation would use PBuffers internally and you would get at least the same speed

No. PBuffers are "Supposedly" faster when it comes to uploading the texture data to the graphics card, not faster at rendering. Basically as far as i understand with a PBuffer it doesn't apply the same algarithums which would be used normally to speed up rendering(If im correct ones to turn the data into whatever format the graphics card likes internally). So uploading is meant to be faster but rendering is meant to be slower, so they couldn't use PBuffers in the drivers for normal textures because applications would run slower.
Im only going by what iv read. Never used OpenGL ES.
