Absolutely. The scorpions, the roof, the bank, the siege, the breakthrough, that crazy bastard left behind...But whole finale is equally good imo, not just the walk.
OUTIW is one of ther greatest in history of any genre too, of course,
Sticking to spags, I wanted to mention Tepepa, but I see you've already done that too. I also agree with everything said about that one.
Another one is For a Few Dollars More. Very minimalistics and mixed with roto credits, but what a great iconic sequence it is.
