Kinda. I only discovered bullet journaling last summer. So I got a dotted Leuchtturm in September, and it only lasted a month because I hated it; I need actual lines to write on. So in October I got a graph-ruled one. I like they system, but not drawing out spreads all the time. So after watching some videos from Yukiko Sakamura and one from The Paper Addict, I just got a Hobonichi Weeks to use as a bullet journal. I only just got it today, so I don't know for sure how it'll work out. But I copied this week's spread from my current journal to the Weeks, and that worked nicely.
