"Trippy" is so relative. No weed is like acid (even "acid" phenos) but some can get really strong in their own way.
If it's for the change in perception (visuals, sounds, wonderland) - the SE Asians seem to excell.
For a mental (thinking) trip - Durban will fry your brain with stimulation (not really pleasant in higher doses, strange body sensations, muscle spasms and pressure in the head).
If you are after emotions - the highland oaxacan (and I guess the related S. Americans) can make you roll on the ground with laughter or want to kiss the sky.
They are all trippy.
