Blender users are too self contained as a community and they also tend to have this mindset where they reject other software "the I want to do everything in blender" attitude, "but blender can do anything other programs can hurr durr" , "it's the artist. not the software" which contributes a lot to the overall quality they produce. That means that what is considered good is usually good only by blender community's standards, not general modern cg standards.
And the ones that say they do good work in blender usually do most of the work in other programs and use Blender only minimally(look at Ricco Ciliers, most of what he does is done in Zbrush/Substance painter but it's a lot easier to get noticed on Blender groups, isn't it? )
Pic related: two top rows, one from Zbrushcentral the other from Blenderartists - maybe at a first glance it's not obvious but there is a gulf between the two in terms of quality.
