And you would still get all of the above mentioned comments (and the picture with a tadpole lodged in your brain which is not something the protagonist would ever see od be acutely aware of if we talk brain looks) whether or not you use the tadpole powers because the whole premise of protagonists story is the tadpole in PCs brain in the first place (used or unused).
Also the danger of ceremorphosis persists with one or more tadpoles used or not (I would however make an exception for the Astral tadpole here which - it is actually made quite clear brings you a few steps closer to becoming a mind flayer)
