MDA is much more like rolling with a trippy last 3+ hours.
6-APB is like a very trippy roll for 8+ hours. It's not quite as lovey but just as sensual.
I'd take 6-APB over MDA any day of the week. The APB's have a way of tickling the receptors after the magic is gone. The only edge MDA has over 6-APB for me is the fun of thinking "ahhh I'm coming down" then being thrown a trip fest of shape shifting people.
