Trent has been brilliant I reckon. I like his "moxy", but he does need to learn a bit more discipline, which will come with maturity. He gets my vote ahead of Clyne.
Yes, he played very well against City, much much better than Clyne against United which was a much weaker team. It's true that Clyne will not be at his personal best after so long out of the game, however, can we afford to give him games to recover as every game is crucial now + we have 3 players ahead of him in that position, ie, Trent, Milner and Fabinho, all much more match fit than him. I think he has been loaned out to get fitter so that we have more options to keep or sell in the summer.
