Sigh... completely different styles, plus the guy nitpicked inferior BV images and compared them with FF's better works. BV also had several visceral and dirty fight scenes with Conan, yet the painter used some of BV's less detailed creations to prove his point.
You do not have to put a number on everything and determine who is "best" and why... This isn't a competition.
Everyone have different tastes. Both guys have unique style, nothing to discuss about this.
