Had to look up the effects of both. From my understanding Baby Woodrose is considered morning glory as well, but there are tons of plants with the same name and different psychoactive effects. Ultimately, Baby Woodrose seemed more interesting. I'm not that into psychedelics but from the trip reports I read on Erowid, this one seemed pretty intense, which is how I like it if I'm going to trip (the only other psychedelic I enjoyed was DMT).
GBL or Triazolam.
