Does anyone use modes other than P,Av,Tv,M on Canon DSLRs?

Somewhat the same end game, different paths.

Right and the different paths don't much matter. My Leica SL only has Manual and Aperture Priority and that's fine too. What matters is that when it's time to take the photo I determine the exposure the shutter speed, the f/stop and the ISO. What paths to that end the camera provides would not influence my decision to purchase and use the camera.

Not totally correct, in any of the priority modes the camera has to maintain control of at least one setting (aperture, shutter or iso) in order to arrive at an exposure calculation. EV adjustments alter the camera parameters, but it still needs to be able to adjust at least one setting. The algorithms are looking at balancing the exposure for the best exposure to produce an image. Forcing one or two settings to the extreme could also force the remaing setting to a less than ideal setting.

And those algorithms need to be user overridable -- on all my cameras they are, over a more than sufficient 10 stop range from -5 to +5. I set the exposure, I select the shutter speed and I select the f/stop. I can of course do that in Manual, but on my cameras I can arrive at the exact same settings using Program mode or Shutter Priority or Aperture Priority in which case the paths don't much matter -- I get the same result regardless.

Grabbed my Oly Pen E-PL9 and snapped a photo of a pepper plant in the garden. In Program mode the camera selected 1/250, f/10 at ISO 200. I know better and I set a different exposure by using the EC control which I set to +1.7. The camera then selected 1/160, f/7.1. I overrode that using P shift and set 1/250, f/5.6. Then in Aperture priority I set f/5.6 and in Shutter priority I set 1/250. It matters little how I got to the right exposure.

Forcing one or two settings to the extreme could also force the remaing setting to a less than ideal setting.
