Yes, use the circle mark on the crank sprocket for TDC. When the manual says that the cam sprocket oval should be facing up, that does not mean 'vertical up' but in line with the 'engine centerline up', which is canted slightly to the rear. The oval makes a good sight hole for the top nub of the valve cover seal on older 2.2L/2.5L engines.
I have found that the timing mark can move after a new belt installation due to the belt not being 'axially seated' on the sprockets. By turning the engine crankshaft over two full turns after belt installation and rechecking the marks, you may find that they are no longer lined up and may be a couple of teeth off. The service manual should state this as part of the procedure after the belt is installed.
