I haven't completed Mark's route yet, as he's being covered by a YouTuber I'm watching, but Ken and Gabriel's routes were very good. I'm excited for the next updates, and I'll check out the side stories once the youtuber finishes what's there of Mark's route cause I'm pretty sure he'll be involved from what I accidentally caught from the not-so-well-hidden spoilers below.
oh i watch him vivian jade, drakewinggaming, fallenwolf. depends who done video and game. blaidd is good for these kind of games but seems to be slower to do videos. vivian is good if you can get past some of the humor and stuff. drakewinggaming good but videos kinda short to me and stops at odd times because uses timer and stops after that. since you asked him thought you would like to know some i follow i guess.
