Beaten both 16m and 8m hard mode. 16 is significantly more difficult. Literally beat 8man HM in 3-4 pulls, 16man HM took about 20. I suppose it could be fielding a 16m roster provides a diluted player skill base, even taking that into consideration I'll firmly say 16m as much more difficult. Also, whoever said that thing about story mode being on par with hard mode obviously has no clue, Kephess is many many many times more difficult on hard mode.
8man kill photo is down for some reason will correct it soon
