Sheyan felt that it was a pity he would not see the Uruk-hai Lurtz here. Based on the timeline, after Lurtz had killed Boromir, he immediately encountered Aragorn who had the MC plot armour. He ended up being stabbed a few times and had his head chopped off with a sword!

Based on Sheyan's observation along the way, perhaps because all nine Ringwraiths would be participating in this war, as well as a few hundreds of the mighty Trolls, there were not many exceptionally strong Uruk-hai – he saw none that were even on Lurtz's level. However, the commander of the army was still an Orc. To be more specific, it was their king, Gothmog.
