Steve/GN strikes me as the annoying guy who just waits you for you to make a mistake and then shouts GOTCHA and makes a video exposing why you're an idiot to the world. There's just this weird antagonistic tone/vibe I always get from Steve's video. (IMHO LTT and GN are both great at what they do, and that's why they're both successful.)
Edit: this is also a "there's no such thing as bad publicity" situation. GN makes a 44 minute long video about this (lol) and I'm sure LTT will make at least one reply video. If they go back and forth, it's just more content and clicks for both of them. Win win.
