I haven't watched anything from Jack beyond his Uncharted 4 let's play. He's one of those YouTubers were I'll watch something of his a couple times in a few months. I do really like him though.

Where has with Mark I'm always excited to see what he uploads.

I like both, but Jack starts to grate on me after a while because he's so sensitive to what commenters say and tends to ramble on and on over something trivial. Meanwhile, Mark dgaf and that's refreshing.
