If the question is does having a bigger cock feel better to its owner, then I'd say, "No"; the feeling is probably the same for all sizes of penises. However, it's been posited that a smaller cock would feel more intense sensation since there would be more nerves per square inch. The latter statement is based on the supposition that the total number of nerves in a penis remains the same regardless of size.
If the question is does having a bigger cock feel better to the partner, then I'd say probably, "Yes". I've had a few women, one being my first wife, say that a larger penis gives greater stimulation and sense of fullness to the vagina. Of course, a penis can be so large it produces pain. It's a matter of personal preference.
