My favorite? The T90 has always been mine, even (especially) after I foolishly sold my first one after five or six years when I finally heed the call of autofocus.
There are many others I love, Nikon F4, EOS 1V and F1N preeminent amongst them. I would dearly love to have a Contax RTS III, but I have other misuses for my money. I have a special affection for cameras with knobs, T90 and 1V notwithstanding.
