I got Valley on it's release day and I've been praticing on it, well unlike Canyon, you need to avoid drifting at any costs (except on very, very sharp curves) on the dirt roads, the car gets more sensitive and you can make sharper turns without needing to drift (which is really neat)
The game is beautiful, there is a lot of variety between tracks, the soundtrack is amazing, it have a lot of clean energy to it, and well I only played the solo mode and multiplayer the most so far, and I can already tell that it's better than Canyon
