Both methyl and adenosyl are called coenzymated forms of cobalamin. It is thought that methyl is converted to adenosyl when needed. I have seen claims that people with liver disease or damaged livers, do better when adenosyl is taken with the methyl. Also some body building sites prefer the adenosyl form.
It tends to be a bit more expensive, but there are not many other major differences.
The cyano which doctors inject is neither.
I think you are speaking about Cerefolin NAC?
Here is a link to it:

NAC is a precursor to glutathione production.
It has a very high dose of methylfolate per tablet.
It would be advisable to take this product on an empty stomach to assure that the methylB12 is absorbed properly.
