I don't think that logic follows. 1P may be weaker than acid for you but it will always be the same strength, so no ugly surprises. And for many people, price and availability are a huge plus for 1P. For me, LSD is hard to get, expensive, and a mystery when it comes to dosage.
That's not to say I wouldn't do other drugs, including acid. I can and I do. Variety is much more interesting.
Sure - makes sense. But i like being able to take the same dose as my friends - or as recommended by someone i know and trust - and have confidence that some weird metabolic quirk won't make some huge difference in efficacy.
The logic, as i see it, is that knowing approximately what sort of effect a dose is likely to have (between individuals) is safer and more reliable than something that (from reports i've read) can vary wildly between people - thus, to me at least, LSD fits the criteria of "better option for high quality acid".
Like i said though; i havent tried 1p-LSD.
But i like - for example - being able to give a dose to friends, particularly those who aren't psych "hard-heads" like myself, with confidence my suggested dose will be right for them.
I gave someone more mushrooms than they could handle once, and it was a very unpleasant night for all concerned, so i've learned to treat psychedelics with a great deal of respect.
It's important to be able to gauge the potency of drugs as powerful as these, to some extent.
Experimental psychonaut dosing regimens may be all fun and games for some of us, but some people are much more fragile than others. For that reason alone, i'd stick with LSD, given the choice between the two.
