Mescaline, 6-APBD, and MDA are all better to me but it will come to down to personal preference.
What do you mean powerful?
Which provides the strongest feeling of empathy. I disagree about the dosage. Phenibut is supposed to have empathogenic effects but I felt nothing at low, moderate or heavy doses, just a bit dizziness and insomnia. That's likely because lovey effects are a coincidental side effect of a drug whose primary purpose is something else. MDMA is basically an amphetamine with empathogenic effects. I've tried hard to look for a pure one but it seems no such thing exists. There actually is an analog completely devoid of speedy effects but oddly enough the feelings of love and empathy were far less than MDMA, so I'm beginning to think the amphetamine speediness is necessary to force the brain into such a stage.
@Doc- I know you didn't ask me but I consider Mescaline and Mescaline containing cacti more empathogenic than a traditional psychedelic.
It does depend on the form and cacti used however. San Pedro is very empathogenic whereas Bridgesii was not as much for me.. Cacti tea is more empathogenic than a full spectrum A/B extract. It all depends, but 9 times out of 10 it's more empathogen than psychedelic for me.
One of my greatest rolls ever involved mdma and San Pedro and I don't think I would have reached that level without the Pedro. I've got the trip report elsewhere online, I don't think I've ever had an experience of any substance impact the way that experience did.
Coincidentally that experience was also 3 days after Shulgins death and it was held somewhat in his honor. Life changing..
As for phenibut, it's empathogenic in the same way alcohol or GHB is.. I consider them all to have empathy associated with em, but I still wouldn't consider them empathogens. It seems GABA-B drugs tend to be more empathy inducing though (ghb and phenibut) and many mdma users love to mix them in when they roll. I'm actually going to be trying phenibut and mdma in a few weeks so I'll report back.
My last experience with phenibut was pretty good actually and with 7.5mg d-amphetamine and some caffeine mixed it was somewhat akin to a roll, but mainly the social aspect moreso than anything.

^^This is true, empathogen can mean different things to different people. Also GABA effecting drugs indirectly effect serotonin from my poor memory.
As for the Mescaline, is it extracted or synthetic? Either way it's a beautiful substance, enjoy it and cherish it because it's not easy for even people in the know to get much. Dosage plays a role in its effects too, larger doses become more and more psychedelic but there is always that empathogenic effect in the background. Very jealousit's been awhile since I've had higher purity Mescaline.
Also Mescaline empathy is different than MDXX empathy. It's more focused on Mother Nature than on other humans like mdma does. All the sudden you can relate to the flowers, the insects, the trees.. It's beautiful. And the afterglow can go on for months sometimes if done right.
Although synthetic pure Mescaline is said to a bit cold and stimulating compared to extracted Mescaline or tea.

Regarding AMT, I was trying to say that it qualifies as a pretty powerful entactogen/empathogen in its own right, easily as much so as MDMA, although its full-on psychedelic at the same time, I've found it ideal for both getting into a state suitable for psychological work on oneself via its entactogen side, and providing the insight and creative mindset to make best use of it thanks to its psychedelic effect.
