Look at pictures of each.
Taughtness of all panels? Wrinkles?
The precision with which panels are cut and sewn determines this.
Being off very very little can result in wrinkles ,particularly in cuben which doesnt stretch.
It may not affect actual performance. But it might affect resale or pride.
Look at Locusgear Khufu for comparison as well. Locusgears net tents appear as taught as their tents. Its a show of what can be accomplished with attention to detail.
You will probably find, it appears that more $$$ are crafted to a slightly higher level
I think Bearpaw is an honest company, that brings fast service, fast customization of gear, etc to the market. They most certainly have a place. Their reputation is good on service. They have a few sporadic complaints about stitching neatness in the past on here.
Personally, I would need a fairly significant discount to MLD's pricing, or be in a fix to choose their shelter over an equivalent MLD one.
