What is the difference between reciting the Quran (tilawah) and chanting it rhythmically (tartil), and which of them is more recommended?

Recitation (Tilawah) generally means reading and encompasses three levels: Tartil (the best of them, with slow, deliberate reading and comprehension), Hadr (fast reading while observing the rules of Tajwid), and Tadwir (an intermediate level). Tilawah also means following the Quran and acting upon it, such as deeming lawful what it declares lawful and unlawful what it declares unlawful, and interpreting it as it was revealed. Thus, Tartil is one level of Tilawah, and Tilawah is a general term that includes both reading and following.
