tTwo recent experiences makes me want to totally reshuffle my top-5.
1-the very best psychedelic experience there is in my opinion: ayahuasca combined with mushrooms (cyanescens).
The mushrooms add something of a warmth or positive vibe to the whole experience, making it feel like you have the best of shrooms, ayahuasca and LSD combined.
It is like ayahuasca with better visuals, and the euphoria of LSD.
Also, less 'drunken-sailor' coördination and manouvreability.
2-peyote and san-pedro combined in large amounts. (purely peyote is probably better, but also more expensive. Nevertheless the peyote takes over and dominates this combo)
Peyote gives a cleaner, and more colourfull experience than san-pedro. Large amounts are extremely visionary and euphoric at the same time. It totally lacks anxiety and intimidation.
3-ayahuasca.
Life-changing insights and experiences. Yet, so intimidating, immersive and mercyless that it ranks at no 3 instead of 1. It simply rides over you like an unstoppable psychedelic freighttrain, but it's heavenly and divine at the same time.
4-shrooms.
Deep psychedelic. Not as deep though, as ayahuasca, and not as euphoric as number 1 and 2.
5-LSD.
Of all psychedelic's, LSD gives the smoothest, cleanest ride. It is more euphoric than 3&4, yet will not be as deep, insightfull and overwhelming.
When combined with passionflower (caapi might very well be even better) it will share the 4th place with mushrooms, being just slightly less visionary and deep as ayahuasca.
if this LSD-combo has joined the shrooms at no4, there is room left for a new no5. This would be oral cannabis. It can in many ways rival with LSD, if taken in the right amounts.
In some aspects it's superiour to LSD (physical sensations, psychological impact, aural sensations) and in some aspects it's inferiour (especially in the visual field).
It can give you a bit of a hangover, though. You will not feel as reborn the day after as with LSD, so it doesn't realy deserve to be prefered over acid. Combined with LSD it is absolutely fantastic, but then you have the question whether i should place it under the category 'acid combo's' or 'cannabis combo's'. There is a great synergy between the two, anyway.
