Which is more deserving of leading the prayer: the one who performed tayammum or the one who performed wudu'?

Question:
He says: Honorable Shaykh, may Allah grant you success. If two men are equal in their recitation and jurisprudence, but one has performed tayammum and the other has performed wudu', which of the two is more deserving of leading the prayer in this situation?

Answer:
The school of thought holds that the one who performed wudu' is given priority, but the correct view is that they are equal, because tayammum is a valid form of purification when there is an excuse, so he is just like the one who performed wudu'.
