Amanitas are enjoyable, albeit peculiar.  One thing I would note is that they can carry a very heavy initial body load.  I would agree with polytrip on the urine statement, although, I find that prior to drinking my urine, if I go walk around, I will feel incredibly emboldened and incredibly energetic.  I remember thinking, on my first experience, "wow, I have so much energy, I could totally see how the vikings could have used these to induce berserker rages".  All that would be necessary to my mind would be the appropriate stimulus, a target for the excess energy to be released as rage.

Additionally, I have never found these to be highly visual. They definitely affect my thought processes and optical processing, but it is markedly different from the more commonly used psychoactives.  On the whole, I would say they are enjoyable, definitely intriguing and worth exploring, but they fail to achieve the same level of submersion as psilocybin, mescaline, lsd, DMT, etc. Even for dream states, it does not even begin to approach the dreams/visions of a weaker ayahuasca experience.

I haven't combined them with anything else, but could definitely see the potential.
