My main problem is that I don't watch videos fro the personality I watch them for the content, many 'tubers put WAY too much emphasis on themselves and much less on their content, additionally many of them do things that actively detract from the quality, like reading Every. Single. Line. which is even worse when a guy reads female lines, which either is either super incongruous or accompanied by a super annoying falsetto.
A common thing I use to guestimate quality is if they use a face cam or have their face on the thumbnails, if they do then actual content is obviously not the main focus so I tend not to spend much time checking their stuff.
