I have done them all. I'll compare them to mushrooms. I have done 4AcODMT as well but only in the 15mg range, not enough for a real strong trip.
Here goes:
Mushrooms make me feel like I'm a child again. Everything is new. Zero anxiety. Visuals and patterning is definetly there and very enjoyable, but not extremely pronounced. It's more the inner vision that become clear. It's very spiritual for me, and makes me feel I'm a part of something larger. Social interaction is somewhat difficult, because the ability to form coherent sentences can disappear.
4HOMET can be as spiritual as mushrooms for me, but this is not the case for my friends. They trip a few times a year, I do it at least once a month. I think that has to do with it.
It is definetly extremely euphoric and very clear-headed.
It is extremely visual, maybe the most of the 4HO's for me, especially open-eyed. It's also empathogenic, in that it reminds me a bit of MDMA in the case of social interaction.
It makes me look at myself with a smile, seeing all my flaws and at the same time giving me the strength to say "I know what I have to work on, and I'm not afraid to turn it around."
on 50mg I had complete egoloss, seeing only white light with my eyes completely opened. That's when the whole Universe was made clear to me. It's been more than two years and I still feel like this was
a turning point in my life. 4HOMET taught me to just do my best for myself and the people around me, there's really nothing more I can do.
I need LOTS of water on this one.
4HOMIPT is situated between 4HOMET and mushrooms. Let me clarify:
In terms of visuals, it is more visual than mushrooms, yet less than 4HOMET. I also get more CEV on 4HOMIPT and more OEV on 4HOMET.
There is less mindfuck than mushrooms, but more than 4HOMET. Communication is impaired like mushrooms, and it doesn't feel as clear-headed as 4HOMET.
On the comedown of 25mg my ego loosened A LOT (I wouldn't say I lost it) and connected to the inner core of the Universe.
4HODET is something else entirely, IMO. Of course every one of these compounds stands on its own. I don't like it when people call these things "not as good as mushrooms" because they can be, maybe even more so because dose is easier to control.
4HODET feels like my body is brought into a meditative state, where the boundaries of my ego are diffcult to maintain. This is also the case with mushrooms for me but more so with 4HODET.
Visuals are there but not extreme. It lasts not as long as the others 4-5 instead of 6-7hours.
From all these, I find 4HOMET best suited for a "party", few people, listening to music.
Mushrooms are for introspection when being alone.
4HOMIPT is for introspection, with another close friend maybe.
4HODET is when you want to explore yourself, alone, going very deep. I believe this one has the most therapeutic potential. Although they all could be used in that setting, IMO.
** When comparing visuals, I compare it to the feeling of clear-headedness, rather than dose.
All of these combine nicely with MXE, and 4HOMIPT (20mg) with 2C-E (20mg) was a massive visual treat. I watched the clouds for 3 hours or so

edit:
This is from a personal file in which I write down general effects of tryptamines. It is not meant as comparison as such, just some extra info.
4HOMET
effects: euphoric, empathic, very visual, very beautiful, cleaner headspace than with mushrooms, cleanest ever, (maybe apart from 25cnbom). at 50mg: massive euphoria, dancing felt won-der-ful, erotic enhancement present

, synhesthesia. true soul cleanser. 100% human. Very playful and Very deep at the same time. true celebration of being (yourself). be your own jesus

. just try to do your best.
(stimulant), euphoriant, empathogen, (entactogen)
like psilocin; "funnier", milder on the mind. more up-beat (as where psilocin is more down to earth).
4HOMIPT
effects: happy, very mushroom-like, intense visuals, synesthesia. marvellous body high (accupuncture-like). headspace between mushrooms and 4HOMET; true sense-distorter/morpher, meditative help. OBE.
(euphoriant), "plastic"
Sense-enhancing psychedelic, slightly stimulating
Mushrooms
Psychedelic, more earth-bound and less abstract than LSD.
4HODET
effects: emotionally neutral, intense, physical, psychotherapy. look at your own mamal/reptilian/rational/sociosexual/... brain/soul
Psychedelic with significant physical side-effects at high doses.
