I believe that both movies are excellent, especially as films that sound too gimmicky to work on their own. Yet, Host, from British co-writer and director Rob Savage, and Unfriended, directed by Levan Gabriadze (and even its more grounded 2018 sequel, Unfriended: Dark Web), make clever use of their concepts, turning limitations into strengths with satisfyingly unique results. However, in my opinion, only one proves to be the more unique and satisfying horror film.
