I still use a 4x5" Cambo for still-life studio shots and occasional landscape. Still film because I can justify spending several years worth of mortgage payments on a digital back.
I still love my Mamiya RZ-67 for portraits or any studio stuff I don't need perspective correction or scheimpflug correction.
Pretty much everything else is my digital SLR or my phone. The latter I keep locked in my car and the former I have on me all the time so they are used the most.
My favorite would likely be the Large format just for the amazing amount of flexibility it has, regardless of it being by far my least used camera.
