I’m suspect of their claim as I was in the 3D printing subreddit as well and never witnessed anyone suggesting the Ender printers were the printer to buy. They’re just dirt cheap so many people buy them as a first printer, but even die hard Ender users will tell you they’re not great to own without tons of mods.
I’ve definitely witnessed this phenomenon in other subreddits though (HomeNetworking > Ubiquiti, Headphones > AudioTechnica).
