I was asked for a comparison between 6-APB and 5-MAPB and will post it here, because the person in question has no space left in their inbox
I've had 6-APB like 3 or 4 times, each time with more or less 5-APB in the mix. From what I remember:
1) I hated the fact that 6-APB wasn't snortable

For 5-MAPB this isn't a problem, although snorting too much will fuck up the nose for about one week.
2) Taking 6-APB oral caused me much nausea, one time I took too much (not effect-wise but for my stomach) and had to vomit, not very pleasent. Due to snorting being an option for 5-MAPB I only tried orally one time and experienced no such thing.
3) In comparison 6-APB is definitely more psychedelic and visual, although I've never had THAT muich visuals with 6-APB.
4) IMHO empathy is much more pronounced with 5-MAPB than with 6-APB/5-APB. So is euphoria.
5) In conclusion I find 5-APB/6-APB are much more something unique, somewhat psychedelic, more a little trip with some MDMA-esque effects. I've only had MDMA 2 or 3 times, but from what I remember 5-MAPB comes pretty close.
I'd choose 5-MAPB over 6-APB any day.
