I would not think Game Mode is the best option for regular Tv for reasons mentioned by @AndrewL. Depends on preferences but personally I would not recommend Dynamic Mode as whilst brighter and punchier (which some obviously like) ,some colours can be exaggerated and lack finer detail. However may be more natural if you tweak some of the settings.
Well as usual with Samsung TVs I got the odd bit of judder so I've put it back in game mode , tweaked colour etc etc and I've got a picture now that I like and no judder at all , top tip if you want no judder use game mode !! Cheers guys
