i think its better for sure, most the super8 people see is shot from a shitty camera, bad film stock, filmed on an auto camera, transfered bad, or transfered by using a projector and filming that. i dont have a problem with that, i think "shitty" looking super 8 looks awesome, and makes for really cool looking footage.
but when people know how to film with it, use a good film stock, and send it to a really good place to get the transfer done, it can look like 16mm, but still wtih a little hint of that super8 look so it looks amazing.
even mediocre 8mm looks better imo, id much rather watch any film footage over another overly sharp oversaturated, video game looking, staring at the sun its so bright look that seems to be so popular right now (such is life).
