B&W film responds very well as B&W developer is what develops the latent image. E6 developing responds very well to pushing because E6 first developer is a B&W developer doing nothing more than developing the latent B&W image. The five steps following the first developer are typically left alone unless some wild effects are wanted. Color neg film has only one developer, a B&W/color developer combination followed, typically, by only one step, a bleach/fix combo. C41 is extremely easy to process. It's easier than B&W. But because of the way the developer and film are constructed, pushing is very iffy. I have pushed it very successfully, but more than one stop is not good. I sometimes extend the development step by 15% (1/2 stop) to help build up some contrast in flat situations. In these situations, I expose at the factory ISO. With normal contrast subject matter, I always give a half stop more exposure than the ISO speed rating. MHO, JB
