a standard dose of smoked dmt is stronger than a standard dose of ayahuasca in the sense of visual intensity
with smoked dmt, all the visuals are very very fast, and they end much quicker too.. with a bigger dose of ayahuasca or with a big dose of oral freebase dmt+maoi, one can get to near the same intensity of smoked visuals, but with all a bit slower, and lasting longer, which means you can understand/interact more with it
the point is, even if visuals is a big part, the experience is way more than only visuals..
for me smoking dmt is getting shot up by a cannon into the psychedelic dimension, and then quickly gravity pulling me back in.. On the way I see amazing landscapes objects and beings, but its just too fast to make much sense of it or come back with a specific lesson. It´s more a reminder of how reality is much more than what we consider. With ayahuasca, I walk up the mountain to see the view of the other dimension, so on the way I have time to notice my own weaknesses, stop at particular points of the way and investigate more, etc.. So I end up bringing much more practical teachings, things to do when back in ´normal´ life, but given the right dosage set and setting, also a lot of visuals, fractals, beings operating me and what not.
So.. DMT in general more and faster visuals that end quick
ayahuasca not so much visuals, more learning, lasts longer
DMT is easier to be abused imo because anybody can get shot up a cannon, but with ayahuasca not so much, because those who cant climb the mountain will suffer and stop in the middle of the way.
