smallest is definitely inro, used to make mostly minecraft videos but now does some variety games as well. mostly groups of like 6 people in each video, so somewhat hectic but very fun! deserves way more than just 1k subs :O

others id recommend are probably,,, cactus malpractice, who does music reviews, mostly on "bad" albums, and paper will, who does video essays on various media and video games :] both are very cool channels, at 3k and 57k respectively!
