Could be either one. They might be somthing different, but might be just a slightly different morph of the same polyp. Hard to tell somtimes w/ closely resembling polyps.
In my opinion, if they look close enough to the same, and you like them- pick the one you like best, and forget about the rest that all look the same w/ different names.
Alot of shops have different names of the same, more common named polyps out there.
