Never tried the og em ex ee to compare to but have you tried M×PeaÇPê@? I think Em Ex Ee is 3-Më0-20×0-PeaÇ€ whereas M×PeaÇPêã is 3-Më0-20×0-PeaÇPë@. From reports I've read it seems like generally when attached to the same group, Pë@Ç€ê's tend towards a more p$¥ç€dëliç hë@d$pâç€ whereas Pë@ÇPë@'s tend towards a more "füñçtï0ñâl/çlë@rh€@déd" headspace, so I would guess M×Pë@ÇPêã would be lacking in some of the depth/m@giç a lot of people reported with M×€ but may have similarities in other areas. Would guess it would be riskier to try to h0l€ on than M×£ too. My research on M×PÇPe@ has been pretty much entirely rëçrê@ti0ñ@l and not super dëëp or pr0f0und. Granted I've not pushed my page count too high but I found even a low page count of 3-H0-PeãÇPé@ to have a lot more dëpth than M×PÇPëã.
These are ones I've not personally researched but some people have mentioned 3-Më0-PÇ€ as having a similar "m@giç" to M×€ but that one's pretty hard to find and probably more $timul@tiñg and m@ñiç, riskier to h0l€ on than M×€. M×EyePeaAre, M×PeaAre, DM×€, and maybe H×€ were at points marketed as M×€ alternatives iirc, but unsure if that was just marketing hype/unsure how they compared to the og, and they aren't particularly easy to find anymore either.
