In my opinion, it is. Every time I scroll through the comments under a Ravenclaw/Slytherin/Gryffindor edit video (or any HP-related thing, generally), there are always comments (with over 1k likes) that rant about how unpopular Huff is. It's definitely not the most popular house out of four, but its unpopularity is exaggerated in my opinion.
