That's a good question, but it's hard to answer because there just isn't enough research done on them. Laboratories are just starting to get permission to perform testing on them, so I feel we will see a lot more information come along in the next few years.
The most common psychedelic mushroom that you will generally find available will be P. Cubensis. There are many different "varieties" of this mushroom mainly based off the size, shape, color, or origin. A very common one is "Golden Teacher," named for it's coloring, but there are lots of others. Amazonian, Australian, Mexican, B+, the list goes on and on. Strength can vary between batches grown, but generally all P. Cubensis shrooms are in the same range of strength. One exception is "Penis Envy," or "PE" mushrooms. These tend to be nearly twice the strength of a normal Cubensis. The high is comparable between varieties, but some people believe that no two trips are the same.
There are a lot of other magic mushrooms, but not many others are often cultivated. If you get shrooms that were grown by someone, you are most likely buying Cubensis and will have the same sort of high as any other. You might get a particularly strong or weak batch, but stories of a different type of high are mostly anecdotal.
