Best lens for architectural photography

I have used and own various tilt/shift and shift lenses as well as large format camera with endless numbers of adjustment ability.

I've gotten the best results from stitching images in PTGui and setting the perspective line. Before you spend the money do yourself a favor rent the 24 and use any wide angle lens and stitch the same area and compare results.  My suggestion is to buy a used zeiss 28 CY and use an adapter on your camera. Once you figure out your nodal point setting you can crate amazing architecture images that will beat any TSE lens.
