When someone shoots down any new but possibly similar to past products with X was better or I'd rather use/watch/play X replies/comments mostly to people that don't know what that thing was.
Commonly used by arrogant and obnoxious rabid fanboys to compare and shill for an already extremely popular to begin with that it doesn't even need even more promotion product.
Usually those who are unable to accept that not everyone will like the big thing they love to suck off for.
Examples
OMG the new OnePlus is amazing!
Shillparing Person:It's gonna suck. Just buy an iPhone.
Big Hero 6 was phenomenal
Shillparing Person:That movie sucked go watch The Iron Giant
Gumball is one of my favorite cartoons
Gumball is shit go watch Spongebob
I love modern cartoons
Shillparing Person:You have bad taste go watch 90s/2000s shows
Animation is one of my favorite mediums
Shillparing Person:Anime is better
Nintendo Switch is fun
Shillparing Person:Sell your switch and buy a PS5
I liked Chip N Dale Rescue Ranges
Shillparing Person:Roger Rabbit is an actually good movie
