Which is better after the Maghrib prayer: Tasbih and Tahlil or delivering a lesson from Riyad al-Salihin?

Teaching religion to people is a religious obligation, and it is better than glorifying Allah (Tasbih) or declaring His oneness (Tahleel). This is based on the Prophet Muhammad’s (peace be upon him) saying: "Convey from me, even if it is a single verse," and his saying: "Seeking knowledge is an obligation upon every Muslim." One can combine the two by dedicating a short time to remembrances (dhikr) after prayer, and then begin the lesson of knowledge, because the superiority of a scholar over a worshiper is like the superiority of the moon over all other planets, and like the superiority of the Prophet over the least of you.
