Neither, because all of this is very subjective. 4-Ho-MET lacks depth, but 4-Aco-DMT lacks energy and can be a bit rough sometimes. Where I to choose only one of the 2 as my only chemical ever, I'd go with 4-Aco-DMT. A good compromise between the 2 would be 4-Ho-MiPT
Both good, just depends on what you are looking for. The 4 aco is super euphoric and makes me feel retarded with long periods of the giggles. The 4 ho is one of the most visual chemicals I've ever had, much more so than the 4 aco in my experience. It isn't near as intense a trip as the 4 aco though.
As others have said 4-HO-MET is much more visual while 4-AcO is more "spiritual" but can also be very visual in higher doses. IME 4-HO has kind of a rough come up with a slight bodyload and anxiety but that only lasts for an hour or so.
We don't allow "What should I take?" threads here, as it's all down to personal opinion, and what might be a lovely drug for another person might really be unenjoyable for you or vice versa.
