witch time mode is the hardest?


Don't think this has a straightforward answer, as it varies for different people. What you heard about blitz is inaccurate because for most players below a certain level, blitz rating < rapid rating. I don't think it's because blitz is intrinsically hard but rather because of the stronger pool. Bullet it depends on if it's your thing or not...many people find it hard and stressful, but many people find it fun. I know a guy who's 1800+ rapid, 1400 bullet, and blitz much higher than bullet. Contrary to popular misconception, bullet isn't "just about flagging" or "random" when you get above a certain level but it's certainly a very different kind of game.
