As far as I understand it's a matter of usage scenario. GIN is extremely
slow on updates, I seem to remember somewhere that it's actually often
better to simply recreate the complete index than to update it; GiST's
write performance is not half as bad. On the other hand, GIN is much
faster on reads than GiST. If you've got some data that is read-only in
nature, you'll probably fare better with GIN. If you need frequent
updates, GiST ist the better choice. In certain scenarios you would use
partial indexes to have a GiST index on current, still heavily updated
data, and a GIN index on older, "archived" rows which are not updated
any longer.

Kind regards
