The two are fairly different, actually.

8+8 was originally proposed by Dave Clark, and it was splitting the IPv6
address into two fields, a 64-bit globally unique identifier in the low part,
and a locator in the high part.

GSE was an enhancement to that done by Mike O'Dell in which the high order
parts (of both source and destination) were massaged by border routers to
achieve various things. It brings a number of additional capabilities, but at
the cost of making the location<->identity binding even harder to secure.
(Unless you just throw your hands in the air and use authentication on all
packets, at which point the address becomes irrelevant.)
